VISUAL RESEARCH METHODS
Part – A
1. Unaided recall
·
Unaided recall is a part of marketing
research technique which is used to gauge the effectiveness of a brand
·
It is to determine how well a consumer remembers an
advertisement without any external help such as clues, or visuals.
2. Aided recall
·
Aided Recall is a tool to measure
the effectiveness of the brand
· Its recall among the consumers when they are given cues.
3. Confounding variable
·
A confounding
variable is an “extra” variable that
you didn't account for.
·
· Amount of food consumption is a confounding variable
4. Reflexivity
·
Reflexivity generally refers to the
examination of one's own beliefs, judgments and practices during the research process.
· Reflexivity is the process of reflecting on yourself the researcher, to provide more effective and impartial analysis.
5. Tabulation
·
Tabulation is a systematic & logical
presentation of numeric data in rows and columns
· It facilitates comparison by bringing related information close to each other
6. Variable
·
A variable is
a characteristic or feature that varies, or changes within a study.
· If a study is investigating the differences between males and females, gender would be a variable
7. Ex post facto
·
Ex post facto study or after-the-fact research is a category of research design in which the
investigation starts after the
fact has occurred without interference from the researcher.
· Ex - How weight influences self-esteem levels in adults. Here pre-existing characteristic (weight) was used to form the groups.
8. Participant observation
·
The participant observation means watching the events or
situation or activities from inside by taking part in the group to be observed.
· He freely interacts with the other group members, participates in various activities of the group, to study their behavior
9. Non participant observation
· When the observer observes the group passively from a distance without participating in the group activities, it is known as non-participant observation.
· Here he/she does not try to influence them or take part in the group activities.
10. Primary data
·
Primary data is a type of data that is collected by researchers directly from main
sources through interviews, surveys, experiments, etc.
· A primary source is an original source that documents an event in time, a person or an idea.
11. Secondary data
·
Secondary data refers to data that is collected by someone
other than the user.
· Common sources of secondary data include censuses, information collected by government departments, organizational records, etc.
12. Diagnosis
·
A diagnosis in
practice is a sequential process starting with a patient with a particular set
of signs and symptoms.
· Diagnostic research should aim to quantify the added value of a test to clinical information that is commonly available before the test will be applied.
13. Descriptive research
·
It describes the characteristics of the population or
phenomenon studied.
· It focuses on describing the nature of a demographic segment, without focusing on “why” a particular phenomenon occurs.
14. Triangulation
·
Triangulation is a method used to
increase the credibility and validity of research findings.
· It can help ensure that fundamental biases arising from the use of a single method or a single observer are overcome.
15. Sampling error
·
Sampling error is a statistical error that
occurs when an analyst does not select a sample that represents the entire population
of data.
·
Sampling error occurs because a
portion, and not the entire population, is surveyed
·
16. Probability sampling
· A probability sampling method is any method of sampling that utilizes some form of random selection.
· It assures that the different units in the population have equal probabilities of being chosen
17. Non probability sampling
·
Non-probability
sampling is a sampling
technique where the chances of any member being selected for
a sample cannot be
calculated.
· Non-probability sampling does not involve random selection
18. Semiotics
·
Semiotics is an investigation into how meaning is created and how meaning is communicated.
·
Meaning is communicated verbally, non-verbally and visually
· Example - Traffic signs, emojis, logos, etc
19. Sign
·
The
sign is the object that combines the signifier and the signified into a
meaningful unit.
· The sign is the relationship between the concept and the representation of that concept.
20. Signifier
·
The
signifier is the sound associated with or image of something (e.g., a tree)
· Any material thing that signifies, e.g., words on a page, a facial expression, an image.
21. Signified
· The concept that a signifier refers to
· The signified is the idea or concept of the thing (e.g., the idea about a tree).
22. SPSS
·
· It's used by various kinds of researchers for complex statistical data analysis.
23. ANOVA
·
The acronym ANOVA refers
to analysis of variance
· It is a statistical procedure used to test the degree to which two or more groups vary
24. Validity
·
Validity refers to how accurately a method
measures what it is intended to measure.
· If research has high validity, that means it produces results that correspond to real properties, characteristics, and variations.
25. Cohort study
·
A cohort study is a particular form of longitudinal study
that samples a cohort.
·
It is a type of panel study where the individuals in the panel
share a common characteristic.
· Examples - A group of people born during the same period of time, like a generation and a group of people who begin schooling at the same time
26. Analytical Survey
·
Two or more variables are usually examined to test research
hypotheses.
· The results allow researchers to examine the interrelationships among variables.
27. Define survey
·
Survey is a list of questions aimed to get data from a
particular group of people.
· Surveys may be conducted by phone, mail, via the internet, and face-to-face
28. Interview schedule
·
The interview
schedule is used by the interviewer during a face-to-face
interaction
· An interview schedule is basically a list containing a set of structured questions that have been prepared to serve as a guide for interviewers
29. Experimental group
·
An experimental
group is a group that
receives a treatment in an experiment.
· For example, a human experimental group could receive a new medication, a different form of counseling, or some vitamin supplements.
30. Sample
·
A sample is a
group of people, objects, or items that are taken from a larger population for
measurement.
· The sample should be representative of the population to ensure that we can generalize the findings from the research sample to the population as a whole.
31. Data coding
·
Coding of data refers to the process of transforming collected
information or observations to a set of meaningful, organized categories.
· Coding is a process of identifying a passage in the text or other data items (photograph, image), searching and identifying concepts and finding relations between them.
32. Reliability
·
Reliability is a way of assessing the quality of
the measurement procedure used to collect data in a dissertation.
·
The greater the degree of consistency and stability in a
research instrument, the greater the reliability.
33. Index
·
Indexes are used to quickly locate data
without having to search every row in a database table
· Indexes can be created using one or more columns of a database table, used for both rapid random lookups and efficient access of ordered records.
34. Reception analysis

A hypothesis is
a precise, testable statement of what the researcher(s) predict will be the
outcome of the study.
· A hypothesis is a tentative statement about the relationship between two or more variables
37. Null hypothesis
·
A null
hypothesis is a hypothesis that
says there is no statistical significance between the two variables in
the hypothesis.
·
The null
hypothesis is often denoted H0
· Ex – I am going to win Rs. 1,00,000
38. Alternate hypothesis
·
An alternative hypothesis is one in which a difference (or an effect) between two or more variables is
anticipated by the researchers
·
The alternative hypothesis, denoted by H1 or
Ha
· Ex – I am going to win Rs. 1,00,000 or more
39. Discrete variable
·
Discrete variables are numeric variables that have a countable
number of values between any two values.
· A discrete variable is always numeric. For example, the number of customer complaints
40. Internal validity
·
Internal validity is the extent to which
a study establishes a trustworthy cause-and-effect relationship between a
treatment and an outcome.
· Internal validity also reflects that a given study makes it possible to eliminate alternative explanations for a finding.
41. External validity
·
External validity refers to the extent
to which results from a study can be applied (generalized) to other situations,
groups or events.
· The validity of the experiment depends on the experimental design.
42.
·
A control group is
used to establish a cause-and-effect relationship by isolating the effect of an
independent variable.
· Researchers change the independent variable in the treatment group and keep it constant in the control group. Then they compare the results of these groups
43. Sequential sampling
·
Sequential sampling is a
non-probabilistic sampling technique
· The process begins, first, with the sampling of a single observation or a group of observations.
44. Sampling frame

For instance, any of the following could be a unit of analysis in a study:
individuals, groups, and artifacts (books, photos, newspapers)
46. Sampling unit
·
A Sampling unit is
one of the units selected
for the purpose of sampling.
· Each unit being regarded as individual and indivisible when the selection is made.
47. Chi-square
·
The Chi-Square test is a statistical
procedure used by researchers to
examine the differences between categorical variables in the same population.

·
A process or record of research into the development of a
particular person, group, or situation over a period of time.
· For example, a case study in medicine may examine a specific patient a doctor treated, and a case study in business might study a particular firm's strategy.
52. Guttmann scale
·
The Guttman scale measures how much of a
positive or negative attitude a person has towards a particular topic.
·
For example,
on a 5-point quiz, if a person gets to question 3 and then stops, it implies
they do not agree with questions 4 and 5.
53. Bibliography

·
Example - the denotation for “blue” is the color blue.
· Rose is a flower
58. Symbol
·
Symbols take
the form of words, sounds, gestures, ideas, or visual images and are used to
convey other ideas and beliefs.
· For example, a red octagon may be a symbol for "STOP". On a map, a blue line might represent a river.
59. TRP
·
TRP is a Television
Rating Point. It is the tool that tells us which channel and the
programme is viewed the most.
· It shows how many times people are watching a channel or a particular programme
60. Dependent variable
· The dependent variable is the variable being tested and measured in an experiment
· It is 'dependent' on the independent variable.
· The researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent variable.
61. Independent variable
· A variable whose variation does not depend on that of another.
· The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable.
· Two examples of common independent variables are gender and educational level.

An abstract summarizes,
usually in one paragraph of 300 words or less, the major aspects of the entire paper in a prescribed sequence
·
It includes 1) the overall purpose of the study and the research problem(s)
2) the basic design of the study; 3) major findings
66. Framing
·
Framing describes the practice of thinking
about news items and story content within familiar context.
· Framing expands the research by focusing on the essence of the issues at hand rather than on a particular topic
67. Perception
·
Perception is a mode of capture reality and
experience through the senses
· Researchers are able to understand multiple realities that are socially constructed based on these perceptions.
68. Factor analysis
·
Factor analysis is a statistical
method used to describe variability among observed, correlated variables
· Factor analysis aims to find independent latent variables.
69. After-only with control
·
This design involves establishing two matched
samples or groups of respondents.
· There is no measurement taken from either group before the experimental variable is introduced
70. Construct
·
The construct is
a proposed attribute of a person that often cannot be measured directly
· Constructs are also discussed under other labels, such as theoretical constructs or latent variables.
71. Moderator
·
Moderator is a qualitative or quantitative
variable
·
It affects the direction and/or strength of the relation
between an independent and a dependent variable.
72. Icon
·
Icon is used to represent a particular category of an object,
even animals.
·
Icon is similar to the actual product and anyone can tell
what it stands for because of similarities.
· Ex - My computer icon in computer desktop
73. Metaphor
·
The use of metaphors in
qualitative research provides
an opportunity to examine phenomena from a unique and creative
perspective.
· Metaphors can be used to provide structure to the data; to understand a familiar process in a new light; and to evoke emotion.
74. Observed frequency
·
It is the actual
frequency that is obtained from the experiment
·
· For example, when rolling a die ten times and then count how many times each number is rolled.
75. Expected frequency
·
In probability, the
number of times a specific outcome. is expected to occur in a given number of repeats.
· For example, you roll a die ten times and then count how many times each number is rolled. The count is made after the experiment.
76. Text
·
Textual analysis is a methodology that involves understanding
language, symbols, and/or pictures present in texts to gain information.
· Visual, written, or spoken messages provide cues to ways through which communication may be understood.
77. Latent content
·
Latent content is the underlying
meaning of communications
· Latent content analysis requires that the researcher is closely involved in interpreting and finding meaning in the text.
78. Visual cues
·
Visual cues are a type of sensory cue that is processed by the eye.
· They provide information and insight into how the world or a specific experience is perceived.
79. Concept
·
Researchers generate concepts by generalizing from particular
facts.
· Concepts are based on our experiences and real phenomena
80. Focus group

A focus group is
a market research method that
brings together 6-10 people in a room to provide feedback regarding a product,
service, concept, or marketing campaign.
· A trained moderator leads a 30-90-minute discussion within the group that is designed to gather helpful information.
81.
·
Closed-ended
questions are questions that
can only be answered by selecting from a limited number of options, usually,
'yes' or 'no'.
· Closed-ended questions give limited insight, but can easily be analyzed for quantitative data
82. Open ended question
·
Open-ended
questions are questions that
cannot be answered with a simple 'yes' or 'no', and instead require the
respondent to elaborate on their points.
· Open-ended questions help you see things from a customer's perspective as you get feedback in their own words.
83. Overt
·
Overt observation is where those being
observed are aware of the fact.
· The researcher may still participate in the activity being observed or might play no part and simply observe.
84. Covert
· The subject and individuals in the environment are unaware of the purpose of the observation
· Research participants are deliberately misinformed about what the study is about or they are unaware of their involvement in the study.

Steps
in research process
Formulate a research problem
·
In this
step the researcher goal should be clear that what he / she intend to achieve
out of research.
·
Initially
the problem may be stated in a broad general way
Review of Literature
·
A literature
review is a comprehensive summary of previous research on a topic.
·
The literature
review surveys scholarly articles, books, and other sources
relevant to a particular area of research.

performing experiments on plant growth might report this hypothesis: "If I give a plant an
unlimited amount of sunlight, then the plant will grow to its largest possible
size.”
Research design
·
The research design refers to the
overall strategy of the research in a logical way

Primary data is data that is
collected by a researcher from first-hand sources, using methods like surveys,
interviews, or experiments.
·
Secondary data is a type of
data that has already been published in books, newspapers, magazines, journals,
online portals etc.
Data analysis and
interpretation

Research method |
Research methodology |
The
research method is defined as the procedure or technique applied by the
researcher to undertake research. |
Research

research problem. |
The
research method is nothing but the behavior or tool, employed in selecting
and building research technique. |
Research
methodology implies the science of analyzing, the manner in which research is
conducted appropriately. |
The
research method is concerned with carrying out experiment, test, surveys,
interviews, etc. |

methodology is concerned with learning various techniques which can be
employed in the performance of experiment, test or survey. |
Research
method covers various investigation techniques. |
Research
methodology consists of complete approach aligned towards the attainment of
purpose. |
Research
method intends to discover the solution to the problem at hand. |
Research
methodology aspires to apply appropriate procedures, with a view to
ascertaining solutions. |
4. Objectives of research
·
To gain
familiarity with a phenomenon or to achieve new insights into it.
·
To
portray accurately the characteristics of a particular individual, situation or
a group
·
To
determine the frequency with which something occurs or with which it is associated
with something else
· To test a hypothesis of a causal relationship between variable
5.
Elaborate
on the probability sampling techniques
·
A probability
sampling method
is any method of sampling that utilizes some
form of random selection.
· In order to have a random selection method, you must set up some process or procedure that assures that the different units in the population have equal probabilities of being chosen
Simple Random Sampling
·
The researcher must ensure that all members
of the population are included in a master list and that subjects are then
selected randomly from this master list.
·
These samples are highly representative of
the population
· It can be time consuming and tedious when creating large samples.
Stratified Random Sampling
·
Stratified random sampling is also referred
to as proportional random sampling.
·
The subjects are initially grouped into
different classifications such as gender, level of education, or socioeconomic
status.
·
These classifications should not have any
overlapping subjects.
· From here, researchers randomly select the final list of subjects from the different defined categories to ensure a well rounded sample.
Systematic Random Sampling
· It is a probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval.
· It is to select every 15th name of a list or every 10th house on one side of a street and so on
Cluster (Area) Random Sampling
·
Cluster random sampling is conducted when the
size of a population is too large to perform simple random sampling.
·
In cluster random sampling, the initial
research identifies boundaries.
·
From here, the researcher randomly selects a
number of identified boundaries.
· Researcher use simple random selection to select subjects from the identified areas.
Multi-Stage Sampling
·
It involves a combination of two or more of
the probability sampling methods.
·
Using just one form of probability sampling
does not ensure the randomization necessary to ensure confidence in
results.
· Researchers are able to maintain confidence that they are mitigating (justifying) biases as much as possible.
6. Non probability sampling techniques
·
Non-probability
sampling is a sampling
technique where the odds of any member being selected for a sample cannot be calculated.
· Non-probability sampling does not involve random selection
·
It is a
non-probability sampling method
in which researchers create a sample involving
individuals that represent a population.
·
Researchers choose these
individuals according to specific traits or qualities
·
Example - Dividing the population by
the state they live in, income or education level, or sex
Convenience sampling
·
It is a type of
non-probability sampling method
where the sample is
taken from a group of people easy to contact or to reach.
·
Standing at a mall or a
grocery store and asking people to answer questions would be an example of a convenience sample.
Purposive sampling
·
A purposive sample is where a researcher
selects a sample based on their knowledge about the study and population.
·
Participants are selected according to the
needs of the study
·
Snowball sampling is where research
participants recruit other participants for a test or study.
· For example, people who have many friends are more likely to be recruited into the sample.
7. Different types of data
Primary data
Primary
data is an original and unique data, which is directly collected by the
researcher from a source.
The
attitudes of a community towards health services, evaluating a social program,
determining the job satisfaction of the employees of an organization, are the
examples of primary data
The sources of primary data are chosen specifically to meet the requirements of a particular research
The questions the researchers ask are framed to get the data that will help them with their study
Secondary data
Secondary
data refers to the data which has already been collected for a certain purpose
and documented somewhere else.
Collection
of data from sources such as articles, journals, magazines, books and
periodicals to obtain historical and other types of information, are examples
of secondary data.
They can include information
from the national population census and other government information
secondary data tends to be readily available and inexpensive to obtain
8. Difference between probability and non probability sampling
Probability sampling |
Non-probability sampling |
The sample is selected at random |
Sample selection based on the subjective judgment
of the researcher |
Everyone in the population has an equal
chance of getting selected |
Not everyone has an equal chance to
participate |
Used when sampling bias has to be reduced |
The researcher does not consider sampling
bias |
Useful when the population is diverse |
Useful when the population has similar
traits |
Used to create an accurate sample |
The sample does not accurately represent
the population |
Finding the right respondents is not easy |
Finding right respondent is easy |
9. Tools employed (used) for collection of data
Interviews
·
In-Depth Interviews include both individual
interviews as well as “group” interviews.
·
The data can be recorded in a wide variety of
ways including stenography, audio recording, video recording or written notes.
·
In interviews it is assumed that there is a
questioner and one or more interviewees.
·
The purpose of the interview is to investigate
the ideas of the interviewees about the phenomenon of interest.
Surveys or Questionnaires
·
Surveys or questionnaires are instruments
used for collecting data in survey research.
·
Observation
·
It is collecting data through observation.
·
This can be done directly or indirectly
1.
Descriptive observations: you simply write down what you observe
2.
Inferential observations: you may write down an observation that
is indirect by the subject’s body language and behavior.
3.
Evaluative observation: A judgment from the behavior.
Case Studies
·
A case study is usually an in-depth
description of a process, experience, or structure at a single institution.
·
Generally it involves a mix of quantitative
and qualitative data collection techniques.
Schedules Method
·
The interviewers, along with schedules, go to
the respondents, put to them the questions and record the replies.
·
The respondents have no scope to
misunderstand any question and thereby putting irrelevant answer.
Information from Correspondents
·
The investigator appoints local agent or
correspondents in different places to collect information.
·
They collect & transmit information to
the central office where the data are processed.
10. Significance (importance) of research
·
The purpose
of research is to inform action.
·
Research
must always be of high quality in order to produce knowledge
·
A tool for building knowledge and for facilitating
learning
·
Means to understand various issues and increase
public awareness
·
An aid to business success
·
Research includes scientific and it promotes
the development of logical habits of thinking and organization
·
11. Difference between qualitative and quantitative research
Quantitative
research |
Qualitative research |
Focuses on testing
theories and hypotheses |
Focuses on exploring ideas
and formulating a theory or hypothesis |
Analyzed through Maths and
Statistical analysis |
Analyzed by summarizing,
categorizing and interpreting |
Mainly expressed in
numbers, graphs and tables |
Mainly expressed in words |
Requires many respondents |
Requires few respondents |
Closed (multiple choice)
questions |
Open-ended questions |
Employs strong scientific
control |
Lacks strong scientific control |
It is measurable |
Not usually measurable |
12. Advantages and disadvantages of quantitative
research
Advantages of Quantitative
research
·
A problem or question is examined by forming
a hypothesis
·
Controlled, objective testing and
experimentation ultimately supports or rejects hypotheses.
·
Each step is standardized to reduce bias when
collecting and analyzing data.
·
The results are valid, reliable and
generalizable to a larger population.
·
Quantitative research is advantageous for
studies that involve numbers
Disadvantages of Quantitative
research
·
Measuring phenomena like human behavior in
natural settings is not possible in
Quantitative research method.
·
Survey instruments are helpless to errors
such as mistakes in measurement and sampling techniques.
·
Another disadvantage is that some topics are
too difficult to quantify in numbers.
·
13. Advantages and disadvantages of qualitative
research
Advantages of Qualitative research
1.
Qualitative Research can capture changing attitudes within a target group such
as consumers of a product or service, or attitudes in the workplace.
2.
Qualitative approaches to research are not
bound by the limitations of quantitative methods.
3.
Qualitative Research provides a much more flexible approach. Researchers
can quickly adapt questions, change the setting to improve responses.
4.
It allows researchers to be far more tentative about what areas they
choose to investigate and how to do so.
Disadvantages of Qualitative research
1.
Sample size can be a big issue.
2.
Self-selection bias
may arise where companies ask staff to volunteer their views.
3.
The artificiality of qualitative data
capture.
4. In qualitative approaches, asking about “how” and “why” can be hugely informative, but if researchers don’t ask, that insight may be missed.
14. Types of research design
1.
Descriptive research
design:
·
In a descriptive design, a researcher is
solely interested in describing the situation or case.
·
It is a theory-based design method which is
created by gathering, analyzing, and presenting collected data.
·
This allows a researcher to provide insights
into the why and how of research.
·
Descriptive design helps others better
understand the need for the research.
2.
Experimental research
design:
·
Experimental research design establishes
a relationship between the cause and effect of a situation.
·
It is a causal design where one observes the
impact caused by the independent variable on the dependent variable.
·
It is a highly practical research design
method as it contributes to solving a problem at hand.
·
·
It is often used in social sciences to
observe human behavior by analyzing two groups.
3.
Correlational
research design:
·
It helps researchers establish a
relationship between two closely connected variables. This type of research
requires two different groups.
·
Statistical analysis techniques calculate the
relationship between them.
·
A correlation coefficient determines the
correlation between two variables, whose value ranges between -1 and +1.
4.
Diagnostic research
design:
·
The researcher is looking to evaluate the
underlying cause of a specific topic or phenomenon.
·
This method helps one learn more about the
factors that create troublesome situations.
· This design has three parts of the research: Inception of the issue, Diagnosis of the issue and Solution for the issue
5.
Explanatory research
design:
·
Explanatory design uses a researcher’s ideas
and thoughts on a subject to further explore their theories.
· The research explains unexplored aspects of a subject and details about what, how, and why of research questions.
15. Longitudinal research
·
Longitudinal
survey research involves conducting survey research over a continuum of time
and spread across years and decades.
·
The
data collected using this survey research method from one time period to
another is qualitative or quantitative.
·
Respondent
behavior, preferences, attitudes are continuously observed over time to analyze
reasons for a change in behavior or preferences.
·
For
example, suppose a researcher intends to learn about the eating habits of
teenagers.
·
16. Survey method
·
Survey Research is defined as the process of
conducting research using surveys that researchers send to survey respondents.
·
The data collected from surveys is then
statistically analyzed to draw meaningful research conclusions.
·
It consists of structured survey questions
that motivate the participants to respond
·
This research type includes the recruitment
of individuals, collection, and analysis of data.
·
It’s useful for researchers who aim at
communicating new features or trends to their respondents.
·
Generally, it’s the primary step towards
obtaining quick information about mainstream topics
Survey research methods
There are three main survey research
methods, divided based on the medium of conducting survey research:
·
Online/
Email: Online survey research is one of the
most popular survey research methods today. The cost involved in online survey
research is very low and the responses gathered are highly accurate.
·
Phone: Survey research conducted over the
telephone can be useful in collecting data. Time required in phone survey will
be higher.
· Face-to-face: Researchers conduct face-to-face in-depth interviews in situations where there is a complicated problem to solve. The response rate for this method is the highest, but it can be costly.
17. Case study
·
A case study is a research strategy and an
empirical inquiry that investigates a phenomenon within its real-life context.
·
Case studies are based on an in-depth
investigation of a single individual, group or event.
·
A case study is a descriptive and exploratory
analysis of a person, group or event.
·
A case study research can be single or
multiple case studies
·
Case studies are analysis of persons, groups,
events, decisions, periods, policies, institutions or other systems that are
studied holistically by one or more methods.
·
Process of case study method
Select a
case
·
Once you have developed your problem
statement and research questions, you should be ready to choose the
specific case that you want to focus on.
·
Case studies often deliberately focus on
unusual, neglected, or outlying cases which may shed new light on the research
problem.
Build a
theoretical framework
·
While case studies focus more on concrete
details than general theories, they should usually have some connection with
theory in the field.
·
Case study is integrated into existing
knowledge about the topic.
·
Conduct a literature review of
sources related to the topic and develop a theoritical framework.
·
This means identifying key concepts and
theories to guide your analysis and interpretation.
Collect data
·
Case studies tend to focus on qualitative
data using methods such as interviews, observations, and analysis of primary and secondary sources
·
Sometimes a case study will also
collect quantitative data.
Describe
and analyze the case
·
In writing up the case study, you need to
bring together all the relevant aspects to give as complete a picture as
possible of the subject.
·
Some case studies are structured like a
standard scientific paper or thesis, with separate sections or chapters for
the methods, results and discussion.
·
Others are written in a more narrative style,
aiming to explore the case from various angles and analyze its meanings and
implications
· In all cases, give contextual details about the case, connect it back to the literature and theory.
18. Techniques of developing research questions
1. Determine the requirements
·
The purpose of assignment is important in
framing questions whether it is to evaluate a set of data or to state and
defend an argument
·
2. Choose a topic
·
The best approach is to choose a topic that
you are interested in.
·
If you are interested in your topic you are
more likely to invest more time, effort, and creativity into your research and
writing.
· The greater your interest, the more likely it is that you will produce an assignment that is interesting to read.
3. Conduct preliminary research
·
Before you write your question it is
advisable to read other research papers
·
Reading in order to develop a research
question is different from reading in order to answer it.
· Focus on the main ideas and arguments
4. Narrow down your topic
·
Having conducted some preliminary research now
the researcher has to narrow down his/her topic.
·
It is important to focus on specific issue
within the broader topic
· It is more effective to cover a single issue of a topic in depth than many
5. Write your question
·
After narrowed down the topic the researcher
pay attention to the wording of research question.
·
The research question must outline a clear
task that the researcher will need to complete.
· A good research question requires you to analyze an issue or problem.
19. Process of conducting survey method (in media research)
(1) Define the population and sample
Populations
·
The target population is
the specific group of people used in research. For example: College students,
Working women, House wife, etc
· Survey should aim to produce results that can be generalized to the whole population.
Samples
·
People who are all involved in the research
process are called sample
·
The sample size depends on how big the
population is.
·
The sample should aim to be representative of
the population as a whole.
· Larger sample produce more valid result.
(2) Decide on the type of survey
There are two main types of survey:
A questionnaire, where a list of
questions is distributed by mail, online or in person, and respondents fills it
out themselves.
An interview, where the researcher asks a
set of questions by phone or in person and records the responses.
The
type of survey depends on the sample size and location, as well as the focus of
the research.
(3) Design the
survey questions
·
The researcher need to decide which questions
to ask and how to ask.
·
Closed-ended questions give the respondent a
predetermined set of answers to choose from. Ex – yes or no questions
·
Open-ended questions are best for qualitative
research. This type of question has no predetermined answers to choose from.
Instead, the respondent answers in their own words.
(4) Distribute
the survey and collect responses
·
Create a clear plan for where, when, how, and
with whom the researcher will conduct the survey.
·
Determine the number of responses.
·
The data collection can be done through mail,
online, or in person.
(5) Analyze
the survey results
·
Researcher has to process the data, usually
with the help of a computer program to sort all the responses.
·
Researcher should also clean the data by
removing incomplete or incorrectly completed responses.
·
If it is open-ended questions, researcher has
to code the responses by assigning labels to each response and organizing them
into categories or themes.
·
Statistical analysis is usually conducted
using programs like SPSS or Stata.
(6) Write up
the survey results
·
The analyzed data is written as thesis, dissertation or research
paper.
·
In the methodology section, researcher
should describe exactly how he/she conducted the survey.
· They should explain the types of questions used, the sampling method, when and where the survey took place, and the response rate.
20. Data tabulation
·
The process of placing
classified data into tabular form is known as tabulation.
·
A table is a systematic
arrangement of statistical data in rows and columns.
·
Rows are horizontal
arrangements whereas columns are vertical arrangements.
(1) Simple Tabulation - When
the data are tabulated to one characteristic, it is said to be a simple
tabulation or one-way tabulation. Ex - Tabulation of religion
(2) Double Tabulation
- When the data are tabulated according to two
characteristics at a time, it is said to be a double tabulation or two-way
tabulation. Exam
(3) Complex Tabulation - When the data are tabulated according to many characteristics, it is said to be a complex tabulation. Example - Religion, sex and literacy, etc. are in one table is an example of a complex tabulation.
Importance of data tabulation
·
Under tabulation, data is divided into
various parts and for each part there are totals and subtotals
·
Relationship between different parts can be
easily known
·
Since data are arranged in a table with a
title and a number so these can be easily identified and used for the required
purpose
·
Tabulation makes the data brief & can be
easily presented in the form of graphs
·
Tabulation presents the numerical figures in
an attractive form
21. Sampling error
· A sampling error is a statistical error that occurs when an analyst does not select a sample that represents the entire population
· Error occurs when the researcher does not understand who they should survey.
· A frame error occurs when the wrong sub-population is used to select a sample.
· Non-response errors occur when respondents those who do not respond.
· Sampling Errors occur because of variation in the number or representativeness of the sample that responds.
· Sampling errors can be controlled by (1) careful sample designs, (2) large samples, and (3) multiple contacts
22. Experimental research
·
Experimental research is a scientific
approach to research
·
It is based on the comparison between two or
more groups with a straightforward logic.
· Experimental research is research conducted with a scientific approach using two sets of variables.
Identifying a research problem
·
The process starts by clearly identifying the
problem you want to study
· Choose the method you want to test, and formulate a hypothesis to predict the outcome of the test.
Planning an experimental research study
·
The next step is to devise an experiment to
test your hypothesis.
·
The amount of time funding you have will also
determine the size of your experiment.
Conducting the experiment
·
At the start of an experiment, the control
and treatment groups must be selected.
· This makes the study a quasi-experiment, since the researchers cannot control all of the variables.
Analyzing the data
·
You must devise a scale by which you will
evaluate the data you receive
·
The researcher must decide what indicators
will be, and will not be, important.
· The researcher has made judgments on what signals improved writing.
Writing the research paper
·
Once the experiment is completed, the
findings should be shared by publishing academic paper.
·
These papers usually have the format to
present the data – Example APA
Advantages of
experimental research
·
The
results are specific.
·
After
analyzing the results, you can apply your findings to similar ideas or
situations.
·
You can
identify the cause and effect of a hypothesis.
23. Strength and weaknesses of Observation method
Strengths
of Observation method
·
Information about the physical environment
and about human behavior can be recorded directly by the researcher
·
Collect data where and when an event or
activity is occurring.
·
Does not rely on people’s willingness or
ability to provide information.
·
Allows you to directly see what people do
rather than what people say.
Weaknesses
of
·
The environment, event or behavior of
interest may be inaccessible and observation may simply be impossible.
·
People may, consciously or unconsciously,
change the way they behave because they are being observed.
·
Observations can never provide us with a
direct representation of reality.
·
It can be expensive and time-consuming
compared to other data collection methods.
· It does not increase your understanding of why people behave as they do.
24. Types of interview
Unstructured interviews
·
These are interviews that take place with few interview
questions.
·
They often progress in the manner a normal conversation
would, however it concerns the research topic under review.
·
It is a relatively formless interview style that researchers
use to establish rapport and comfort with the participant, and is extremely helpful
when researchers are discussing sensitive topics.
·
The researcher is expected to investigate participants in
order to obtain the most rich and in-depth information possible.
·
We have to conduct several rounds of interviews with your
participants in order to gather all the information we need.
· It is a part of the conversational style this interview method requires.
Semi
structured interviews
·
It is mostly a guided conversation between
the researcher and participant.
·
It does maintain some structure, but it also
provides the researcher with the ability to investigate the participant for
additional details.
·
It offers a great deal of flexibility for the
researcher.
·
We can get more details about participants’
thoughts, feelings, and opinions.
Structured
interviews
·
These are interviews that strictly adhere to
the use of an interview protocol to guide the researcher.
·
It is
·
As a result, there are not a lot of
opportunities to investigate and further explore topics that participants bring
up when answering the interview questions.
·
It helps target the specific phenomenon or
experience that the researcher is investigating.
· It helps to gather the correct information that the researcher need
25. Data analysis for qualitative research
Content Analysis
·
It can
be used to analyze the documented information from text, images, and sometimes
from the physical items.
·
It
depends on the research questions to predict when and where to use this
method.
Narrative Analysis
·
This
method is used to analyze content gathered from various sources such as
personal interviews, field observation, and surveys.
·
The
majority of times, stories, or opinions shared by people are focused on finding
answers to the research questions.
Discourse Analysis
·
Discourse
analysis is used to analyze the interactions with people.
·
·
Discourse
analysis also focuses on the lifestyle and day-to-day environment while
deriving any conclusion.
Grounded Theory
·
It explains
why a particular phenomenon is happened
·
Grounded
theory is applied to study data about the host of similar cases occurring in
different settings.
· When researchers are using this method, they might alter explanations until they arrive at some conclusion.
26. Data analysis in quantitative research
Descriptive statistics
·
This method is used to describe the basic
features of types of data in research.
·
Descriptive analysis does not go beyond
making conclusions.
·
The conclusions are again based on the
hypothesis researchers have formulated so far.
· Descriptive analysis is also called a ‘univariate analysis’ since it is commonly used to analyze a single variable.
Here are a few major types of descriptive analysis methods.
Measures of Frequency
·
Count,
Percent, Frequency
·
It is
used to denote how often a particular event occurs.
·
Researchers
use it when they want to showcase how often a response is given.
Measures of Central Tendency
·
Mean,
Median, Mode
·
The
method is widely used to demonstrate distribution by various points.
· Researchers use this method when they want to showcase the most commonly indicated response.
Inferential
statistics
·
Inferential statistics are used to make
predictions about a larger population after research
·
·
It is used to showcase the relationship
between different variables instead of describing a single variable.
Here are some of the commonly used methods for data
analysis in research.
Correlation
·
The
researchers are interested to understand the relationship between two or more
variables, they opt for correlation research methods.
Cross-tabulation
·
It is
used to analyze the relationship between multiple variables.
·
Suppose
provided data has age and gender categories presented in rows and columns. Cross-tabulation
helps for data analysis and research by showing the number of males and females
in each age category.
Analysis of
variance (ANOVA)
·
The
statistical procedure is used for testing the degree to which two or more vary
or differ in an experiment.
· A considerable degree of variation means research findings were significant.
27. Types of variables
Independent variable
· A variable whose variation does not depend on that of another.
· The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable.
· Two examples of common independent variables are gender and educational level.
Dependent variable
·
The dependent variable is the variable being
tested and measured in an experiment,
·
It is 'dependent' on the independent
variable.
·
The researcher is looking
for the possible effect on the dependent variable that might be caused by
changing the independent variable.
·
Independent Variable: Type
of fertilizer given to the plant
·
Dependent Variable: Plant
height
Example 2 - We might change the type of information given
to participants to see what effect this might have on the amount of information
remembered.
In this particular example the type of information is the independent variable and the amount of information remembered is the dependent variable.
28. Writing research report
I. The preliminary pages
·
In the
preliminary pages, the report should carry the cover page such as title, name
of the researcher, acknowledgements and declaration.
·
Then
there should be a table of contents followed by a list of tables and list of
graphs or charts, if any, given in the report.
· A brief synopsis of the research can also be added in a crisp and concise manner.
II. The main text
a. Introduction: This section should contain a clear statement of the
objective of the research and an explanation of the methodology adopted in
accomplishing the research. The scope of the study along with practical
implications should as well be stated in this part.
b. Review of literature - This section should contain detailed
discussion of the past research or studies carried out in related field of
study.
c. Research Methodology - A section can fully be devoted to
describing the methodology and the method adopted of fulfilling the objectives
of the study. Sampling technique, sample size, qualitative or quantitative
method and data collection are mentioned here.
d. Findings and Recommendations - The essence of this section is to present
the findings and recommendations in non-technical language.
III. The end matter
·
Bibliography
or references, i.e., list of books, journals, reports, etc., consulted, should
also be given in the end.
· At the end of the report, appendices should be enlisted in respect of all technical data.
29. Characteristics of good research
·
The
objective or the purpose of the research is clearly defined.
·
The
research process should be discussed in detail and with clarity.
·
Appropriate
research design should be followed keeping the objectives in mind.
·
High
ethical standard should be adopted at each stage of the research.
·
Data
analysis must be adequate to reveal the truth.
·
Analysis,
findings and conclusions should complement the research objectives.
·
The
study must be reliable, valid and generalizable.
·
Suggestions
are adequate for decision making.
· It must reflect the true picture or reality.
30. Qualitative research
·
Empiricism
: the only knowledge that human beings acquire is from sensory experiences
·
Unstructured
/ flexible / open methodology
·
To
describe variation in a phenomenon, situation, issue, etc.
·
Emphasis
on description of variables
·
Fewer
cases is enough
·
Covers
multiple issues but assembles required information from fewer respondents
·
It is
authenticate
·
Explore
experiences, meanings, perceptions and feelings
· Organization more descriptive and narrative in nature
31. Methods of qualitative research
1.
One-on-One Interview: Conducting in-depth interview is one of
the most common qualitative research methods. It is a personal interview that
is carried out with one respondent at a time.
2. Focus
groups: Usually includes a limited number of respondents
(6-10). The main aim of the focus group is to find answers to the why what and
how questions.
3.
Ethnographic research: It is the most in-depth observational method
that studies people in their naturally occurring environment.
4. Case
study research: It is one of the simplest ways of conducting
research as it involves a deep dive and thorough understanding of the data
collection methods and inferring the data.
5. Record
keeping: This method makes use of the already existing reliable
documents and similar sources of information as the data source. This data can
be used in a new research.
6. Process of observation: Qualitative observation is a process of research that uses subjective methodologies to gather systematic information or data.
32. Quantitative research
·
Rationalism:
Human beings achieve knowledge because of their capacity to reason.
·
Structured
/ rigid / predetermined methodology
·
To
quantify extent of variation in a phenomenon, situation, issue, etc.
·
Emphasis
on some form of either measurement or classification of variables
·
Emphasis
on greater sample size
·
Assembles
required information from a greater number of respondents
·
Reliability
and objectivity
· Explains incidence, nature of issues, opinions and attitude discovers regularities and formulates theories
33. Identifying research problem
Statement of the problem in a general way – All the problem should be stated in a broad way. In case of social research, conducting pilot survey is important.
Understanding the nature of the problem – The best way of understanding the problem is to discuss it with those who first raised the problem and with what objectives in view.
Developing the ideas through discussions – The researcher must discuss the research problem with his colleagues and others who have enough experience in the same area.
Rephrasing the research problem – Finally the researcher must sit to rephrase the research problem into a working proposition.
34. Writing bibliography for books and journals
A bibliography is a list of sources used when writing a scholarly article or research paper or a list of books or articles an author has published on a specific subject.
For books
1. Name of author, last name first.
2. Title, underlined to indicate italics
3. Place, publisher, and date of publication
4. Number of volumes
Example – Kothari, C. R., Quantitative techniques, New Delhi, Vikas Publishing House Pvt. Ltd., 1978
For journal
1.
Author or authors. The surname is followed by
first initials.
2.
Year of publication of the article (in round
brackets).
3.
Article title.
4.
Journal title (in italics).
5.
Volume of journal (in italics).
6.
Issue number of journal in round brackets (no
italics).
7. Page range of article.
Example - Gray, L (2018), 'Exploring how and why young people use social networking sites', Educational Psychology in Practice, vol. 34, no. 2, pp. 175-194.
35. Hypothesis
·
Hypothesis is developed to talk about the
research problem or to address any phenomenon.
·
It aims to encourage critical approach.
·
·
It further assists in the careful and focused
analysis of data collected.
·
In scientific researches, hypotheses are
developed keeping in view the experimentation and observation drawn from the
past.
· Working hypotheses are based on the widely accepted suppositions in order to carry out further research.
36. Levels of measurement
Nominal level of measurement
·
In this level of measurement, the
numbers in the variable are used only to classify the data.
·
In this level of measurement, words, letters,
and alpha-numeric symbols can be used.
·
Female gender could be classified as F, male
gender could be classified as M, and transgendered classified as T.
Ordinal level of measurement
·
This level of measurement depicts
some ordered relationship among the variable’s observations.
·
Ex - First rank, second rank, third rank and
so on.
·
The ordinal level of measurement indicates an
ordering of the measurements.
Interval level of measurement
·
The interval level of measurement classifies,
orders the measurements, and also specifies that the distances between each
interval on the scale
·
For example, an interval level of measurement
could be the measurement of anxiety in a student between the score of 10
and 11
·
This interval is the same as that of a
student who scores between 40 and 41.
Ratio level of measurement
·
In this level of measurement, the
observations, in addition to having equal intervals, can have a value of zero
as well.
· In the ratio level of measurement, the divisions between the points on the scale have an equivalent distance between them.
37. Semiotics in Advertisement
·
Semiotics is frequently used in advertising to signify an
advertiser's message through the use of signs or symbols.
· In some cases, the sign can be an exact representation of the thing being signified, while in other cases, it may be a symbol associated with it.
Images - One of the most frequent symbols used in advertising is the visual image of the product being sold. For example, a picture of skull and crossbones next to a pack of cigarettes could be used to advertise the harmful nature of cigarette smoking.Text - One word will convey a message with the same effectiveness as an entire picture. For example, boost is the secret of our energy tells that it gives more energy for the players.
Sound - Symbols do not have to be visual in nature. They can be audible, as well. The jingle is used to attract the target audience and an easy symbol to recall. Example- Airtel music
Visual effects (VFX) – It is the process by which imagery is created or manipulated outside the context of a live action shot in ad film making. We could see VFX in detergent soap and powder advertisements to show the cleanliness of dress
Process - Semiotics employs the use of repeated symbols that come to signify the product. Advertisers do this, not only through repetition, but also through the combining of symbols, bringing words, images and music together into one meaningful and coherent composition.
38. Types of data analysis
Text Analysis
·
Text Analysis is also referred to as Data
Mining.
·
It used to transform raw data into business
information.
·
It offers a way to extract and examine data
and deriving patterns and finally interpretation of the data.
Statistical Analysis
·
Statistical Analysis shows "What
happen?" by using past data.
·
Statistical Analysis includes collection,
Analysis, interpretation, presentation, and modeling of data.
· It analyses a set of data or a sample of data. There are two categories of this type of Analysis - Descriptive Analysis and Inferential Analysis.
Descriptive Analysis
·
This method is used to describe the basic
features of types of data in research.
·
·
The conclusions are again based on the
hypothesis researchers have formulated so far.
· Descriptive analysis is also called a ‘univariate analysis’ since it is commonly used to analyze a single variable.
Inferential Analysis
·
Inferential statistics are used to make
predictions about a larger population after research
·
For example, you can ask 100 audiences at a
movie theater if they like the movie they are watching. Researchers then
use inferential statistics on the collected sample to reason that about
80-90% of people like the movie.
·
It is used to showcase the relationship
between different variables instead of describing a single variable.
Diagnostic Analysis
·
Diagnostic Analysis shows "Why did it
happen?"
·
This Analysis is useful to identify behavior
patterns of data.
· If a new problem arrives in business, this Analysis find similar patterns of that problem.
Predictive Analysis
·
Predictive Analysis shows "what is
likely to happen" by using previous data.
·
Example -If last year I bought two dresses
based on my savings and if this year my salary is increasing double then I can
buy four dresses.
·
It makes predictions about future outcomes
based on current or past data.
Prescriptive Analysis
·
Prescriptive Analysis determines which action
to take in a current problem or decision.
· Based on current situations and problems, they analyze the data and make decisions.
39. Discuss various steps of item analysis
·
Item analysis is the set of
qualitative and quantitative techniques and procedures used to evaluate the
characteristics of items of
the test
· Its analysis provides information about its performance.
Perform Item Analysis
Example - Multiple-choice question is given to 32
students. To conduct item analysis, you follow the steps below:
·
Keep
ten tests with the highest scores in one group.
·
Keep
ten tests with the lowest scores in another group.
·
For
each test question, count and write down the number of students in the
high-scoring group who select each question option
·
Do the
same for the students in the low-scoring group
·
Compute
the difficulty level of the question
·
Compute
the discrimination index of each question or question option
·
Evaluate
the efficiency of each question option
40. Criteria for good measurement technique
RELIABILITY
·
Reliability
is the consistency of measurement
·
It is
the degree to which an instrument measures the same way each time it is used
under the same condition with the same subjects.
·
In
short, it is the repeatability of measurement.
·
A
measure is considered reliable if a person's score on the same test given twice
is similar.
VALIDITY
·
Validity
is the extent to which a test measures what it claims to measure.
·
It is
vital for a test to be valid in order for the results to be accurately applied
and interpreted.
· Validity isn’t determined by a single statistic, but by a body of research that demonstrates the relationship between the test and the behavior it is intended to measure.
PRACTICIBILITY
·
It
should be feasible & usable.
· Quality of being usable in context to the objective to be achieved.
USABILITY
- Easiness in administration, scoring, interpretation and application, low
cost, proper mechanical make – up
MEASUREABILITY - It should measure the objective to be achieved.
41.
·
The
failure of management and the researcher to specify clear and mutually agreed
upon objectives for the questionnaire.
·
Time
constraint in preparing questionnaire
·
Inexperienced
researcher failure to clearly specify objectives leads to dysfunctional
behavior
·
The
majority of them have questionnaires which are very lengthy.
·
Questions
asked at lower levels in an organization can result in requests for information
or action at another level.
·
Questions
written at a reading level too high for the participants.
·
Major
significance associated with employee involvement in questionnaire development,
especially in grievances, labor disputes, wages, hours of employment or
conditions of work.
· Forget to consider the cost implications of data collections
42. Considerations while framing questions for survey research / Techniques of framing questionnaire
·
The questions should be few, short, clearly
worded, simple and easy to reply.
·
The questions should be within the information
scope of the respondents.
·
The questions should have direct relation to
subject of the investigation.
·
The opening questions should not be such as
to abuse human interest.
·
Units and technical terms are not to be used
in question as far as possible.
·
The questions should be inter-related with
each other.
·
The questions should proceed in logical
sequence moving from easy to more difficult questions.
·
Personal and intimate questions are not to be
included as far as possible.
·
Emotional questions should be avoided.
·
Open-ended questions should be avoided to the
extent possible.
·
The questions should be free from
ambiguity. Vague expressions capable of different interpretations should be
avoided in a questionnaire.
·
Answer to a question should
be objective and have a capacity of easily classified, tabulated and
analyzed.
·
There should be some control questions in the
questionnaire which indicate the reliability of the respondent.
·
Adequate space for answers should be provided
in the questionnaire.
·
Brief directions with regard to filling up
the questionnaire should be given.
· A place in the questionnaire should be provided for the signature of the respondent.
43. Content analysis
Preparation of data – Preparing the collected data for content analysis
Defining the theme – Classifying the content into themes which can be a word, phrase or a sentence. When deciding the unit of analysis, one theme should present an idea.
Developing categories and coding scheme – Develop sub-categories and coding scheme for the analysis (headmaster, mayor, MLA).
Pre-testing the coding scheme on sample – In order to ensure consistency members of the research team need to code the sample of existing data. If the level of consistency is low across researchers then re-coding has to be done again.
Coding
all the text – Applying the coding process to the data.
Drawing inferences on the basis of coding - One has to draw inferences on the basis of codes and categories generated.
Presentation of results – Based on the analysis, the researcher can present the results in the form of graphs, matrices or conceptual frameworks. The result should be presented in such a way that the reader is able to understand the basis of interpretations.
1. Select the content you will analyze
Based on your
research question, choose the texts that you will analyze. You need to decide:
·
The
medium (e.g. newspapers, speeches or websites) and genre (e.g. opinion pieces,
political campaign speeches, or marketing copy)
·
The
criteria for inclusion (e.g. newspaper articles that mention a particular
event, speeches by a certain politician, or websites selling a specific type of
product)
·
The
parameters in terms of date range, location, etc.
·
To
reach media representations of male and female politicians, you decide to
analyze news articles and opinion pieces in print newspapers between 2017 –
2019.
2. Define the units and categories of analysis
·
Unit(s) - Are you going to record the frequency of individual words
and phrases, the characteristics of people who appear in the texts, the
presence and positioning of images, etc
· Categories can be objective characteristics (e.g. female, aged 40-50, lawyer, mother) or more conceptual (e.g. trustworthy, corrupt, conservative, family oriented).
· Your units of analysis are the politicians who appear in each article and the words and phrases that are used to describe them.
3. Develop a set of rules for coding
·
Coding involves organizing the units of
meaning into the previously defined categories.
·
In considering the category female politician
you decide which titles will be coded with this category (governor, counselor,
mayor).
·
With trustworthy you decide which specific
words or phrases related to trustworthiness (honest and reliable) will be coded
in this category.
4. Code the text according to the rules
·
You go through each text and record all
relevant data in the appropriate categories.
·
This can be done manually or aided with
computer programs
· You record the characteristics of each politician mentioned, along with all words and phrases related to trustworthiness that are used to describe them
5. Analyze the results and draw conclusions
·
Once coding is complete, the collected data
is examined to find patterns and draw conclusions in response to your research
question.
·
You might use statistical analysis to
find correlations
·
From these results, you conclude that
national newspapers present male politicians as more trustworthy than female
politicians, and infer that this might have an effect on readers perceptions of
women in politics
44. Visual research
·
Visual research is a qualitative
research methodology that relies on the use of artistic mediums to produce and
represent knowledge.
·
These artistic mediums
include film, photography, drawings, paintings,
and sculptures.
·
The artistic mediums provide a rich source of information
that has the ability of capturing reality.
·
They also reveal information about what the medium captures.
·
·
Images are an essential component for different sorts on
inquires in a wide range of topics
· After the visual material is created the resulting collection may be the base of further discussion, interviews, and or analysis
45. How will you conduct a focus group study?
·
A focus group is
a market research method that
brings together 6-10 people in a room to provide feedback regarding a product,
service, concept, or marketing campaign.
· A trained moderator leads a 30-90-minute discussion within the group that is designed to gather helpful information.
Define a focus group
·
A focus
group is a small group of six to ten people led through an open discussion by a
skilled moderator.
·
The
moderator’s goal is to generate a maximum number of different ideas and
opinions from as many different people in the time allotted.
· A homogeneous group of strangers comprise the focus group.
Designing questions
·
Twelve
is the maximum number of questions for any one group. Ten is better, and eight
is ideal.
·
Focus
group participants won’t have a chance to see the questions they are being
asked
· So the question should be short and to the point using unambiguous words.
Recruiting and preparing for participants
·
In an
ideal focus group, all the participants are very comfortable with each other
but none of them know each other.
·
Homogeneity
is the key to maximizing disclosure among focus group participants.
· Focus group participants can be recruited on the basis of nomination, random selection, job title, etc
Conducting the focus group
·
·
The
moderator facilitates the discussion; the assistant takes notes and runs the tape
recorder.
· It may be important to collect demographic information from participants if age, gender, or other attributes are important for correlation with focus group findings.
Analyzing the data
·
Clean
up transcripts by stripping off nonessential words.
·
Simultaneously
assign each participant comment/quote a separate line on the page as well as
each new thought or idea therein.
·
Label
each line with the participant and group number
· When all comments have been entered, look for common categories or themes across the entries for each question.
46. Control group
·
A control group in
a scientific experiment is a group separated
from the rest of the experiment
·
The independent variable being tested cannot influence the
results.
·
This isolates the independent variable's effects on the
experiment
·
Control groups can also be separated into two other types:
positive or negative.
·
Positive control groups are groups where the conditions of the experiment are
set to guarantee a positive result.
·
A positive control group can show the experiment is
functioning properly as planned.
·
Negative control groups are groups where the conditions of the experiment are
set to cause a negative outcome.
· Control groups are not necessary for all scientific experiments.
47. Design a coding sheet for content analysis
48. Status of audience research in India
·
Broadcast Audience
Research Council (BARC) is the world's largest television measurement
science industry-body.
·
BARC India owns and manages a transparent,
accurate, and inclusive TV audience measurement system.
·
It also provides a suite of Insight products
designed for broadcasters, advertisers and agencies.
·
The Big Data and Insights generated by BARC
India powers efficient media spends and content decisions in a highly dynamic
and growing television sector.
·
It uses Audio
Watermarking technology to measure viewership of TV channels
·
System also allows measurement of
time-shifted viewing and simulcasts.
·
BARC India was planned and executed as an
alternative to TAM Media Research Pvt. Ltd, the audience measurement
system
·
It was set up as per guidelines of
the Ministry of Information & Broadcasting, Government of India.
49. Experimental group or treatment group
·
An experimental
group is a group that
receives a treatment in an experiment.
·
The “group” is
made up of test subjects (people, animals, plants, cells etc.) and the
“treatment” is the variable you are studying
·
For example, a human experimental group could receive a new
medication, a different form of counseling
·
A plant treatment group could receive a new plant fertilizer,
more sunlight, or distilled water.
·
The group that does not receive the treatment is called
the control group.
·
There are two important things in setting up
an experimental group. First what variable you're going to test. Then, how you
are going to measure the results from the experimental group.
· Comparing the results from the experimental group with the results of the control group is one way to measure the results.
50. Significance of pre-testing the research design
·
·
Using
pretest of the survey, researchers are able to ensure that the questions are
clearly articulated and that the response options are relevant and
comprehensive.
·
Pretest
ensures researchers and respondents interpret the survey in the same way
·
Pretest
can bring to light those inevitable instances of obscure terminology,
unfamiliar references and ambiguous words, etc
·
Pretest
allows the researcher to assess the amount of time it takes to complete the
survey
·
Another
important feature of pretesting survey is the technical report left for future
research endeavors.
·
It is
used to design a valid survey instrument
· Pretest process helps avoid future problems encountered at the various stages of study design
51. Phases of mass media research
Phase I
·
Phase I
of the research, the research subject is medium itself
·
What is
it? How does it work? What technology does it involve?
·
Who
will have access to the new medium? How much will it cost?
Phase II
·
The
study about the uses and the users of the medium
·
How do
people use the medium in real life? What is the reason for the usage?
· What purpose they used media? What gratifications does the new medium provide?
Phase III
·
Includes
investigations of the social, psychological, and physical effects of the medium
·
How
much time do people spend with the medium? Does it change people’s perspectives
about anything?
· What do the users of the medium want and expect to hear or see?
Phase IV
·
Research
is conducted to determine how the medium can be improved, what is the impact of
it either in its use or through technological developments
·
Can the
medium provide information or entertainment to more types of people?
·
· Is there a way to change the content to be more valuable or entertaining?
52. Disturbances in research study
·
Research
guides do not have a thorough knowledge of the various methodologies. Before
undertaking research projects, researchers should be well equipped with all the
methodological aspects
·
Poor
communication gets on the way of the progress of the research. It is important
to communicate with the supervisor to clarify the doubts regarding the research
topic
·
Spending
ample time in learning the skills and practical implementation consumes a lot
of time
·
Not
having a deadline can be troublesome during the research journey
·
It can
be difficult to deal with the quantity of literature that one might have
accessed
·
A
literature review has to go beyond being a series of references and citations.
You need to interpret the literature and be able to position it within the
context of your study
·
Insufficiency
of data is a potential problem. Most of the business establishments are of the
opinion that researchers may misuse the data provided by them.
·
Researchers
with low self-esteem feel less motivated thereby affecting the quality of the
work
·
A lot
of time and energy is spent on tracing appropriate books, journals, reports,
etc
· Also many of the libraries are not able to get copies of new reports and other publications on time
53. Significance of semiotic approach
·
Semiotics is generally described as the study of signs
·
These theories are important because they reveal the way in which signs
communicate ideas, attitudes and beliefs to us.
·
In the context of television, film, newspapers and other
forms of media, semiology explains
the way in which images are used to represent and relay information to the
audience.
·
Semiotics is a key tool to ensure that intended meanings are unambiguously understood by the person on
the receiving end.
·
Semiotics can thus be a powerful tool to create awareness,
develop brand associations and add brand values that make a difference in the
market.
·
54. Visual semiotics / Sign in semiotics
· Semiotics is generally described as the study of signs
· Visual semiotics is a sub-domain of semiotics that analyses the way visual images communicate a message.
· Semiotics tries to investigate how images create meaning.
· A sign can be a word, sound, a touch or visual image. A sign has two components: the signifier, which is the sound, image, or word, and the signified, which is the concept or meaning the signifier represents.
Three types of signifiers are
·
An Icon has a physical resemblance to the signified, the thing
being represented. A photograph is a good example as it certainly resembles
whatever it depicts.
·
An Index shows evidence of what’s being represented. A good
example is using an image of smoke to indicate fire.
·
A Symbol has no resemblance between the signifier and the signified.
The connection between them must be culturally learned. Numbers and alphabets
are good examples. There’s nothing inherent in the number 9 to indicate what it
represents. It must be culturally learned.
·
The meaning of sign is created by people
·
Common examples of semiotics include traffic signs,
emojis, and emoticons, etc
·
It is used to increase brand image of a
company
·
Written and spoken language is full of
semiotics in the form of intertextuality, metaphors, etc.
·
Semiotics is a key study
into the evolution of human consciousness
55. Importance of mass media research
·
Mass media research is the study of
information related to any form of mass
communication.
·
It helps business decide which types and forms of
social media are most
beneficial to use for business purposes
·
For health and well-being reasons, mass media research is important
·
It helps scientists find out how mass media impacts people.
·
It helps businesses figure out which forms of advertising
work
·
56. Content analysis advantages and disadvantages
Advantages of Content
Analysis
·
Can allow for both quantitative and
qualitative operations
·
Can provides valuable historical/cultural
insights over time through analysis of texts
·
Can be used to interpret texts for purposes
such as the development of expert systems
·
Is an unobtrusive means of analyzing
interactions
·
Provides insight into complex models of human
thought and language use
Disadvantages of Content Analysis
§
Can be extremely time consuming
§
It is subject to increased error
§
It is often lacking of theoretical base
§
It tends too often to simply consist of word
counts
§
Often disregards the context that produced
the text
§ Can be difficult to automate or computerize
57. Empirical research
·
Empirical research is a type of research
methodology that makes use of verifiable evidence in order to arrive at
research outcomes.
·
This type of research relies solely on
evidence obtained through observation or scientific data collection
methods.
·
Empirical research can be carried out
using qualitative or quantitative observation methods, depending on the
data sample
·
Empirical research carries a scientific
investigation
·
An empirical research is usually divided into
4 parts which are the introduction, methodology, findings, and discussions.
·
The introduction provides a background of the
empirical study while the methodology describes the research design, processes,
and tools for the systematic investigation.
·
The findings refer to the research outcomes
and the discussions highlight the significance of the study and its
contributions to knowledge.
Examples of Empirical Research
· An empirical research study can be carried out to determine if listening to happy music improves the mood of individuals. The researcher may need to conduct an experiment that involves exposing individuals to happy music to see if this improves their moods.
·
An empirical research study can also be
carried out to determine the effects of a new drug on specific groups of
people.
58. Deductive reasoning and inductive reasoning
Deductive
reasoning
·
Deductive
reasoning works from the more general to the more specific.
·
Sometimes this is informally called a
“top-down” approach.
·
We might begin with thinking up a theory about
our topic of interest. We then narrow that down into more specific hypotheses that we can test. We narrow down
even further when we collect observations to address the
hypotheses. This ultimately leads us to be able to test the hypotheses with
specific data – a confirmation (or not) of our original
theories.
Inductive
reasoning
·
Inductive
reasoning moving
from specific observations to broader generalizations and theories.
·
Informally, we sometimes call this a “bottom
up” approach
· In inductive reasoning, we begin with specific observations and measures, begin to detect patterns and regularities, formulate some tentative hypotheses that we can explore, and finally end up developing some general conclusions or theories.
59. Significance of statistical software packages
in research
Quantitative data analysis software
(a) Apache
Spark
·
A
unified analytics engine for large scale data processing
· It also includes a library – MLlib, that provides a progressive set of machine algorithms for repetitive data
(b) Python
·
An
increasingly popular tool for data analysis
· Libraries take advantage of the beauty, flexibility and performance of Python
(c) R
·
A free
software environment for statistical computing and graphics
· It compiles and runs on a wide variety of UNIX platforms, Windows and MacOS
(d) SPSS
(Statistical Packages for Social Sciences)
·
A
general purpose statistical package widely used in academic research for
editing, analyzing, and presenting numerical data
· It is compatible with all file formats that are commonly used for structured data such as Excel, plain text file, and SQL database
(e) Stata
·
A
powerful and flexible general purpose statistical software package used in
research in the fields of economics, sociology, political science
·
It’s
capabilities include data management, statistical analysis, graphics, etc
Qualitative data analysis
(a) NVivo
·
A
qualitative data analysis computer software package produced by QSR
international
· It has been designed for qualitative researchers working with very rich text based and multimedia information
(b) MAXQDA
·
An
alternative to Nvivo and handles a similar range of data types allowing
organization, color coding and retrieval of data
·
Text,
audio or video may equally be dealt with by this software package
·
(c) Atlas.ti
·
Software
for the qualitative analysis of large bodies of textual, graphical, audio and
video data
· It offers a variety of tools for accomplishing the tasks associated with any systemeatic approach to soft data, that is material which cannot be analyzed by formal
60. Explain concepts and constructs with example
Concepts
·
A
concept is a generally accepted collection of meanings or characteristics
associated with certain events, objects, conditions, situations, and behaviors.
·
Classifying
and categorizing objects or events that have common characteristics creates
concepts.
·
We
design hypotheses using concepts.
·
We
devise measurement concepts by which to test these hypothetical statements.
·
We
gather data using these measurement concepts.
·
The
success of research hinges on (1) how clearly we conceptualize and (2) how well
others understand the concepts we use.
·
For
example, when we survey people on the question of customer loyalty, the
questions we use need to tap faithfully the attitudes of the participants.
· The challenge is to develop concepts that others will clearly understand.
Constructs
·
A
construct is an image or abstract idea specifically invented for a given
research and/or theory-building purpose.
·
Typical
marketing constructs are brand loyalty, satisfaction, preference, awareness,
knowledge.
Examples of constructs
·
Brand
awareness – percentage of respondents having heard of a designated brand
·
·
Intentions
of purchase – the number of people who are planning to buy the specified object
within a designated time period
· Importance of factors – what factors and their intensity influence a person’s purchase choice
61. Data distribution
·
A data distribution is a function or
a listing which shows all the possible values of the data.
·
It also tells how often each value occurs.
·
The data in a distribution will be ordered
from smallest to largest, and graphs and charts
·
From a distribution you can calculate the
probability of any one particular observation in the sample space
· The function of a distribution that shows the density of the values of our data is called a probability density function
· There are some statistical distributions that come up so often they have received their own names; One of these is the bell-shaped curve, also called the normal distribution.
62. How do you test the validity and reliability of research instrument?
Testing Validity
Validity refers to
the degree to which an instrument accurately measures what it intends to
measure. Three common types of validity for researchers and evaluators to
consider are.
§
Content
validity – indicates
the extent to which items adequately measure or represent the content of the
property or trait that the researcher wishes to measure.
§
Construct
validity – indicates
the extent to which a measurement method accurately represents a construct and
produces an observation
§
Criterion-related
validity - indicates the
extent to which the instrument’s scores correlate with an external
criterion either at present or in the
future.
Testing Reliability
§
Internal
consistency reliability -
looks at the consistency of the score of individual items on an instrument,
with the scores of a set of items.
§
Test-retest - measures the correlation between
scores from one administration of an instrument to another, usually within an
interval of 2 to 3 weeks.
§ Inter-rater reliability - Common situations where more than one rater is involved may occur when more than one person conducts classroom observations.
63. Qualitative Vs quantitative variables
1. Quantitative
·
A quantitative variable is a
variable that is, the values it can take are numbers.
·
Quantitative variables are divided into two
types: discrete and continuous
(a)
Discrete
·
Quantitative
discrete variables are variables for which the values it can
take are countable and have a finite number of
possibilities.
·
Number of children per family, Number of
students in a class are examples of discrete variables
(b)
Continuous
·
Quantitative
continuous variables are variables for which the values
are not
countable and have an infinite number of possibilities.
·
For example: Age, Weight, Height - A
28-year-old man could actually be 28 years, 7 months, 16 days, 3 hours, 4
minutes, 5 seconds, 31 milliseconds, 9 nanoseconds old.
(2) Qualitative
·
Qualitative variables
are variables that are not numerical and which values fits into
categories.
·
Qualitative variables are divided into two
types: nominal and ordinal.
(a)
Nominal
·
A qualitative nominal variable is
a qualitative variable where no ordering is possible in the
levels.
·
For example, the variable gender is nominal
because there is no order in the levels female/male.
·
(b)
Ordinal
·
A qualitative ordinal variable is
a qualitative variable with an order implied in the levels.
·
For instance, if the severity of road
accidents has been measured on a scale such as light, moderate and fatal
accidents.
· Another good example is health, which can take values such as poor, reasonable, good, or excellent.
64. Different types of observation method for data collection
Structured observation – The observation is characterized by a careful definition of the units to be observed, the style of recording the observed information, standardized conditions of observation and the selection of pertinent data of observation is called as structured observation
Unstructured observation – The observation is to take place without planning of the observation of units, the recording method and the condition is called as unstructured observation.
Participant observation – If the observer observes by making himself, a member of the group he is observing so that he can experience what the members of the group experience, is called participant observation
Non participant observation – When the observer observes as a detached person
without any attempt on his part to experience through participation what others
feel, is called non participant observation
Disguised observation – The observer presence may be unknown to the people he
is observing it is said to be disguised observation
Controlled observation – The observation takes place according to definite pre-arranged plans, involving experimental procedure, it is called controlled
observation
Uncontrolled observation – The observation takes place in the natural setting it is said to be uncontrolled observation.
65.
·
Visual imagery related to
graphics, visual scenes,
pictures, or the sense of sight.
·
Auditory imagery related
to sounds, noises, music, or the sense of hearing.
·
Visual
Image what you get when you recall a vision-related experience from long term
memory
·
Visual
Imagery the representation of perceptual information in the absence of visual
input
·
We use
it to reason and solve problems, especially when things are no longer present
in our visual environment
· It can tell us something about the format of our representation of the world
66. Sources of data collection for case study
Personal interviews
·
It is also called as a face-to-face survey, is a survey method that is utilized when a
specific target population is involved.
·
The main purpose is to explore the responses of the people to
gather more and deeper information.
· It is used to probe the answers of the respondents and at the same time, to observe the behavior of the respondents, either individually or as a group
Direct observation
· It is a method of collecting evaluative information in which the evaluator watches the subject in his or her usual environment.
· It is used when other data collection procedures, such as surveys, questionnaires, etc., are not effective
· When the goal is to evaluate an ongoing behavior process, event, or situation; that can be readily seen.
Psychometric tests
·
Psychometrics is the field of study
concerned with the theory and technique of
psychological measurement
·
It includes the measurement of knowledge, abilities,
attitudes, and personality traits.
· The field is primarily concerned with the study of differences between individuals.
Archival records
·
Archival methods are those that involve
the study of historical documents
·
These preexisting data are gathered by current researchers.
·
67. Differentiate between research question and
hypothesis
RESEARCH QUESTION |
HYPOTHESIS |
Research
questions are used in many fields including literature, and sociology. |
Hypothesis are part of the scientific
research method |
Research questions are always written
as questions. |
Hypothesis are
written as statements. |
For example, a research question
would ask, "What is the effect of heat on the effectiveness of
bleach?" |
A hypothesis
would state, "I predict heat will diminish the effectiveness of
bleach." |
A research question requires less
preparation, but focus and structure is critical. |
Before writing a hypothesis, the researcher must
determine what others have discovered about this subject. |
The researcher
using only a research question will write the answer to the question. |
When writing the conclusion for
research conducted using a hypothesis, the researcher will write whether the
hypothesis was correct or incorrect. |
68. Research is much concerned with proper fact finding, analysis and evaluation. Do you agree?
·
Yes, research is about finding facts, analyzing them and then
evaluating the results.
·
Research begins with a theory or thesis statement.
·
This statement has to be proven or disproven as true/false.
·
It means that research is concerned with finding facts,
analyzing facts and evaluating the response, in order to form a conclusion
regarding the research topic.
·
The ethical, moral,
and scientific belief is that all research has to be based on facts.
·
Theory is proved or
disproved based on what could be found at that time.
·
It goes back to the fact, that proper information, analysis, and evaluation are needed in order to
conduct proper research.
·
Inaccurate facts will skew the data and render the entire
research invalid.
69. Theory of syllogism
·
A syllogism is a kind of logical argument that
applies deductive reasoning to arrive at a conclusion
·
It is based on two or
more propositions that are declared or assumed to be true.
·
Aristotle defines, from the combination of a
general statement and a specific statement, a conclusion is deduced.
·
For example, knowing that all men are mortal
and that Socrates is a man, we may conclude that Socrates is mortal.
·
Syllogistic arguments are usually represented
in a three-line form:
o All men
are mortal.
o Socrates
is a man.
o Therefore,
Socrates is mortal.
·
Facts are determined by combining existing
statements
· Two syllogistic theories are Aristotelian syllogism and Stoic syllogism.
70. Characteristics, sources of data, purposes of case study approach
Characteristics of Case Study
1. The
number of unit to be studied is small.
2. It
studies a social unit deeply and thoroughly.
3. It
is qualitative as well as quantitative.
4. It
covers sufficient wide cycle of time.
5. It
has continuity in nature.
Sources of Data for Case Study
1. Personal
documents, viz diaries, memories, autobiographies, letters etc of the
researcher.
2. Qualification
and interest of the researcher.
3. Life
history of the respondents.
4. Motives and objectives of the study.
Case study purpose
·
Describe
an individual situation (case), e.g. a person, business, organization, or
institution, in detail
·
Identify
the key issues of the case
·
Analyse
the case using relevant theoretical concepts
· Recommend a course of action for that particular case
71.
·
Narration
means how the story is told
·
Narrative
refers to the development of a story, the roles and relationships of the
character within it.
·
For a
film to be a narrative it must present us with a series of events in ways that
suggests connection between one event and the next.
·
Narratives
must be made up of parts that are related usually in a cause and effect way
·
Story
refers to the events of the narrative whereas plot refers to how the story is
presented in terms of order and narrative logic
·
The
story is the ‘what’ in a narrative that is depicted, and the plot is ‘how’
·
The
most significant way plot shapes story is through chronology – the order in
which the story is told
·
Narrative
chronological videos used to show past events, cause and effect, and
psychologically motivated characters
·
Action
is chronological but significant elements of the story are told in flashback,
and some foretelling is used.
· Cause and effect used but less obviously communicated
72. Importance of sign, code and symbol in the
visual analysis
Sign
·
A sign is anything that communicates a meaning
·
Signs consist of three inter-related parts: a
sign, an object, and an interpretant.
·
Smoke as a sign for fire
·
The object is best thought of as whatever is
signified.
·
The interpretant is best thought of as the
understanding that we have of the sign/object relation.
Codes
·
Logical
codes are monosemic (the signifier stands for only one signified)
·
Social
and aesthetic codes are polysemic (the signifier can stand for more than one
signified)
·
Logical
codes are denotative
·
Aesthetic
and social codes are connotative
·
Logical
codes are generally digital
·
·
Logical
codes are conventional
·
Social
and aesthetic codes are either conventional or new
Importance of symbol
·
A symbol is any image or thing that stands for
something else.
· Every word is a symbol for the idea it represents. Flags are symbols for nations.
· Symbols add layers of meaning to a story, poem, or other creative work.
· They enable an author to deliver an idea or message within a narrative, a message on multiple levels.
· In other words, symbols add depth.
73. What is meant by operational definition? Explain its purpose
·
Operational
definition is fundamental when collecting all types of data
·
It describes the variables you will use as indicators and the
procedures you will use to observe or measure the variables.
·
The operational
definition of a variable is
the specific way in which it is measured in that study.
·
An operational definition, when applied to
data collection, is a clear, concise detailed definition of a measure.
·
It is particularly important when a decision
is being made about whether something is correct or incorrect
·
The data collection will be meaningless if
the definition of an error has not been specified.
·
When collecting data, it is essential that
everyone in the system has the same understanding and collects data in the same
way.
·
It should therefore be made before the
collection of data begins.
·
It is necessary to define how to collect the
data.
·
It is easy to assume that those collecting
the data understand what and how to complete the task.
·
People have different opinions and views, and
these will affect the data collection.
· The only way to ensure consistent data collection is by means of a detailed operational definition that eliminates ambiguity.
74. Difference between manifest content and
latent content
Manifest content
·
Manifest content is the concrete
surface content (data).
·
Advantages with manifest
content are ease of testing and reliability and a disadvantage is
its validity.
·
·
Manifest content analysis is concerned with data
that are easily observable both to researchers and the coders
·
Manifest content is evidence that is
directly seen such as the words in
an interview.
·
In
manifest analyses the researcher is thought to maintain distance and separation
from the objects of study
·
Manifest
approach seeking only to describe what is observed
Latent content
· Latent content refers to the underlying meaning of content such as the interpretation of an interview.
· Latent content analysis is defined as interpreting what is hidden deep within the text.
· The role of the researcher is to discover the indirect meaning in participants’ experiences.
· Latent content analysis acknowledges that the researcher is intimately involved in the analytical process
· Latent analyses underscore the importance of the researcher co-creating meaning with the text.
· Latent content analysis, there are two distinct types: latent pattern and latent projective.
· The latent pattern approach seeking to discover an unseen pattern.
75. Explain hermeneutics analysis
·
Hermeneutics is the theory and
methodology of interpretation
·
Hermeneutic research emphasizes subjective
interpretations in the research of
meanings of texts, art, culture, social phenomena and thinking.
·
Hermeneutics is a wider discipline
which includes written, verbal, and non-verbal communication.
·
Hermeneutic research includes various
different approaches.
·
Methods of analysis may also vary
·
Hermeneutic analysis enables us to elicit an in-depth
understanding of meanings of human practices, culture, works of art and texts.
·
Understanding is produced through systematic interpretation
processes.
·
These processes are known as a hermeneutic circle
·
Interpretation of details affects the interpretation of the
entire phenomenon.
· You can combine hermeneutic analysis with other methods of analysis that aim to interpret and understand meanings.
76. Mixed research method
·
Researchers will pair two methods together in
the same study examining the same phenomenon is mixed research method.
·
Example - Researchers will use qualitative
methods to develop quantitative research
·
The benefit of mixed methods is that it
offers a richer picture of a communication phenomenon by gathering data and
information in multiple ways.
Example 1: In
surveys (quantitative), a researcher interested in understanding how a
supervisor sharing personal information with his or her subordinate affects the
way the subordinate perceives his or her supervisor. We could also add
interviews (qualitative) with subordinates.
Example 2: In content analysis, measuring representation of different races (quantitative) during prime time television. While we can count the appearances of members of different races and compare (qualitative) that to the composition of the general population.
77. Explain visual analysis
·
Visual analysis is a method of
understanding art
·
It focuses on an artwork's visual elements, such as color, line, texture, and scale.
·
It is a description and explanation of visual structure.
·
The
purpose of visual analysis is to understand how an artwork communicate ideas,
content, or meaning.
·
Visual
analysis is often used as a starting point for art-historical writing.
·
This is
especially important when exposing hidden ideologies.
Visual analysis can include three phases.
Phase One - Observation
·
Observation
means closely looking at and identifying the visual attributes of an artwork
·
It is
trying to describe them carefully and accurately in own words.
·
Phase Two - Analysis
·
Analysis
requires you to think about your observations and try to make statements about
the work based on the evidence of your observations
·
This
phase encourages students to think about how the specific visual elements
they’ve identified combine together to create a whole, and what effect that whole
has on the viewer.
Phase Three - Interpretation
·
To use
visual analysis as the basis for an interpretation of an artwork, have students
formulate research questions based on what they have observed
· In this phase, students balance observations, description, and analysis with facts about the artist and historical context from trustworthy published sources.
78. How is an interpretative method of analysis applied to images?
·
Interpretive research attempts to interpret
social reality through the viewpoints of the participants
·
These interpretations are heavily
contextualized, and are naturally less generalizable to other contexts.
Criteria that can be used to judge the
rigor of interpretive research.
Dependability -
Interpretive research can be viewed as dependable or authentic if two
researchers assessing the same phenomenon using the same set of evidence
independently arrive at the same conclusions or the same researcher observing
the same or a similar phenomenon at different times arrives at similar
conclusions.
Credibility - Interpretive research
can be considered credible if readers find its inferences to be believable.
Confirmability - Confirmability refers
to the extent to which the findings reported in interpretive research can be
independently confirmed by others (participants).
Transferability - Transferability in interpretive research refers to the extent to which the findings can be generalized to other settings.
79. Communication research
·
· In the field of communication, there are three main research methodologies: quantitative, qualitative, and rhetorical.
(a) Quantitative Research
·
Quantitative research seeks to establish
knowledge through the use of numbers and measurement.
·
The most commonly used methodologies are
experiments, surveys, content analysis, and meta-analysis.
Experiments:
Experiments are an empirical form of research that enable the researcher to
study communication in a controlled environment.
Surveys: Surveys
are often used to collect information from large groups of people using scales
that have been tested for validity and reliability.
Content Analysis: Content
analysis is used to count the number of occurrences of a phenomenon within a
source of media. For example, a researcher might be interested in finding out
if people of certain races are underrepresented on television.
Meta-Analysis:
Researcher takes a collection of quantitative studies and analyzes the data as
a whole to get understand of a communication phenomenon. For example, a
researcher might be curious about how video games affect aggression.
(b) Qualitative Research
·
Qualitative research is interested in
exploring subjects’ perceptions and understandings as they relate to
communication.
·
Qualitative researcher, might interview
students to find out what they like and dislike about a course.
Interviews: This
typically consists of a researcher having a discussion with a participant based
on questions developed by the researcher.
Focus Groups: A
researcher using this method gathers a group of people with intimate knowledge
of a communication phenomenon.
Participant Observation: This
method involves the researcher watching participants in their natural
environment.
(c) Rhetorical Research
·
Rhetorical research is a form of textual
analysis.
·
It involves selecting a text, choosing a
rhetorical method, analyzing the text, and writing the criticism.
·
A researcher could be interested in how women
in management roles are portrayed in television. They could select a group of
popular shows and analyze that as the text. This might result in a rhetorical
essay about the behaviors displayed by these women and what the text says about
women in management roles.
