4.1 Introduction
In the earlier units, you came to know about the marketing research and
marketing information system. In this unit you will study about the research
process and its design.
In this unit you will learn about the first phase in planning the research
project, which is formulating a research design. Based on causality,
research designs have been divided into four categories of exploratory,
descriptive, causal and experimental designs. While exploratory and
descriptive studies provide information on events and attributes from which
inferences can be drawn, they can only offer tenuous conclusions.
Objectives
After studying this unit, you should be able to:
Explain research process
Describe various steps in research process
Define research design
Explain research design types

4.2 Research Design
Research design is “the framework or plan for a study that is used as a
guide in collecting and analyzing the data it is blueprint that is followed in
completing a study.”
Features of research design: Research design
is a plan specifying the sources and types of information relevant to the
research problem.
is a strategy specifying which approach will be used for gathering and
analyzing the data.
also includes the time and cost budgets since most studies are done
under these two constraints.
Need for research design: The various needs of research designs are:
It facilitates the smooth sailing of the various research operations,
thereby making as efficient research as efficient as possible yielding
maximal information with minimal expenditure of effort, time and money.
It gives us a plan in advance of data collection and analysis for our
research project.
It has a great bearing on the reliability of the results arrived at and as
such constitutes the firm foundation of the entire edifice of the research
work.
It helps the researcher to organize his ideas in a form of whereby it will
be possible for him to look for flaws and inadequacies.
Self Assessment Questions
1. Research design is a _________ for a study.
2. Research Design is a plan specifying the _________ and types of
_________ relevant to the research problem.
4.3 Need for a Step by Step Process
A researcher is often required to think a few steps ahead, because various
steps in research process are inter-woven into each other and each step will
have some influence over the other steps. In marketing research, even
though our focus is on one particular step, other interrelated steps of
operations are also being looked into simultaneously. As we complete one
activity or operation, our focus naturally shifts from it to the subsequent one,
i.e. the focus is not concentrated exclusively on one single activity or

operation at any particular point of time. The research process provides
systematic, planned approach to the research project and ensures that all
aspects of the research project are consistent with each other.
Self Assessment Questions
3. A researcher is often required to think _________.
4. The research process provides _____ approach to the research project.
4.4 Steps in Research Process
Figure 4.1: Steps in Marketing Research Process
Being a systematic inquiry marketing research requires careful planning of
the orderly investigation process. Though it is an over simplification to
assume that all research processes would necessarily follow a given
Marketing Research Unit 4
Sikkim Manipal University Page No. 67
sequence marketing research often follows a generalised pattern which can
be broken down and studied as sequential stages.
Figure 4.1 gives the stages in the marketing research process. As shown in
the figure, research process begins with the identification. The research task
may clarify a problem or define an opportunity.
Defining the problem
You should first define the problem clearly since it is of crucial importance in
marketing research as in terms of both time and money research is a costly
process. Careful attention to problem definition allows the researcher to set
the proper research objectives which in turn facilitate relevant and economic
data collection.
Statement of research objectives
After clarifying and identifying the research problem, you must make a
formal statement of research objectives. Research objectives may be state
in qualitative or quantitative terms and expressed as research question
statements or hypothesis. For example, the research objective "to find out
the extent to which the sales promotion programmes affected sales" is a
research objective expressed as a statement. A hypothesis on the other
hand is a statement that can be refuted or supported by empirical findings.
Planning the research design
In this stage you must determine the type of sources of information needed,
the data collection methods (surveys or interviews for example), the
sampling methodology and the timing and possible costs of research. The
design chosen may be exploratory, descriptive, quasi-experimental or
experimental design categories which again include a number of alternative
methods.
Planning the sample
Sampling involves procedures that use a small number of items or parts of
the population to make conclusion regarding the whole population. The first
sampling question that needs to be asked is who is to be sampled, which
follow from what is the target population. Defining the population may not be
as simple as it seems.
Data collection
The data collection process follows the formulation of research design
including the sampling plan. Data which can be secondary or primary can be
Marketing Research Unit 4
Sikkim Manipal University Page No. 68
collected from tools that are classified into two broad categories, the
observation methods and the communication methods.
Data processing and analysis
Data processing begins with the editing of data and coding. Editing involved
inspecting the data collection forms for omission, legibility and consistency
in classification.
Analysis represents the application of logic to the understanding of data
collected about the subject.
Formulating conclusion, preparing and presenting the report
Finally you have to interpret the information for drawing conclusions to be
used in managerial decisions. The research report should effectively
communicate the research findings and need not necessarily include
complicated statements about the technical aspect of the study and
research methods.
Self Assessment Questions
5. The first step in marketing research process is _________.
6. Data processing begins with the _________ and _________.
7. Data which can be _________ or _________.
4.5 Meaning of Research Design
A research design is the framework, a blueprint for the research study which
guides the collection and analysis of data. To be effective, a research
design should furnish at least the following details:
A statement of objectives of the study or the research output.
A statement of the data inputs required on the basis of which the
research problem is to be solved.
The methods of analysis which shall be used to treat and analyze the
data inputs.
The objective is to calculate the margin earned on sales when this
discount is offered and compare it with the margin when discount is not
being offered.
The data to be collected over a period of time

given market? Explain.
Self Assessment Questions
8. A research design should furnish statement of _________ of the study
or the research output.
9. A research design is the framework for the research study which guides
the _________ and _________ of data.
4.6 Types of Research Design
There are four types of research designs which are broadly classified as:
Exploratory Design
Descriptive Design
Causal Design
Experimental Design
Exploratory Research Design: The exploratory research design involves
getting a feel of the situation and emphasises a discovery of ideas and
possible insights that may help in identifying areas of further rigorous study.
For example a food product manufacturer, wanting in introduce a breakfast
cereal may be in knowing the desirable attributes of such a product before
really defining the product concept. The main objective of the exploratory
research is to fine tune the broad problem into specific problem statement
and generate possible hypotheses. It therefore, gives useful direction for
farther research. The exploratory studies are mainly used for:
Providing information to enable a more precise problem definition or
hypothesis formulation.
Establishing research priorities.
Giving the researcher a feel of the problem situation and familiarizing
him with the problem.
Collecting information about possible problems in carrying out research,
using specific collection tools and specific techniques for analysis.
Marketing Research Unit 4
Sikkim Manipal University Page No. 70
Descriptive Research Design: Descriptive research is used to obtain
information concerning the current status of the phenomena to describe
"what exists" with respect to variables or conditions in a situation. The
methods involved range from the survey which describes the status quo, the
correlation study which investigates the relationship between variables, to
developmental studies which seek to determine changes over time.
Description or inference could be quantitative or qualitative in nature.
Descriptive designs only describe the phenomenon under study attempting
to establish a relationship between factors. The data collected may relate to
the demographically or the behavioural variables of respondents under
study or some situational variables. For example, descriptive research
design could be suited to measure the various attributes of successful sales
people, or evaluate a training programme or a retailing situation.
Causal Design: Causal Research explores the effect of one thing on
another and more specifically, the effect of one variable on another.
The research is used to measure what impact a specific change will have on
existing norms and allows market researchers to predict hypothetical
scenarios upon which a company can base its business plan. For example,
if a clothing company currently sells blue denim jeans, causal research can
measure the impact of the company changing the product design to the
colour white.
Following the research, company bosses will be able to decide whether
changing the colour of the jeans to white would be profitable.
Experimental Design: Experimental design provides a stronger and more
reliable basis for the existence of casual relationship between variables.
Here, your aim as a researcher is to investigate the possible cause-and-
effect relationship by manipulating one independent variable to influence the
other variable(s) in the experimental group, and by controlling the other
relevant variables, and measuring the effects of the manipulation by some
statistical means. By manipulating the independent variable, the researcher
can see if the treatment makes a difference on the subjects.

10. _________ Research explores the effect of one variable on another.
11. The researcher in ________ method does not know “what he will find”.
12. Descriptive research can be _________ or _________ in nature.
4.7 Research Design and Marketing Decision Process
The management of an industry or an organisation is involved in taking
decisions about the development or expansion of the concern. No doubt the
concern has to face many problems from time to time. The management
has to overcome or solve these problems. These problems may be
regarding the availability of resources, quality of production, costing,
publicity or promotion, etc. For example, for the publicity of goods
produced, the manufacturer or seller may take the help of TV, radio,
newspapers or door-to-door promotion. Many such endless problems are
there. In each of these decision-making problems, there are some common
components. These are:
Course of Action
States of Nature (Events)
Outcomes
Course of Action: Decision-making problems deal with the selection of a
single act from a set of alternative acts. If two or more alternative courses of
action occur in a problem, then making a decision is necessary to select
only one course of action. In the above example of advertising goods
produced, there are so many alternative courses of actions. The final choice
of any one will depend on the pay-off (or money value) of each strategy
under the circumstances.
Let the acts or actions be symbolised by a1, a2, a3, a4, ...........; then the
totality of all these actions is known as action space denoted by A. For four
actions a1, a2, a3, a4; A = action space = {a1, a2, a3} or A = {A1, A2, A3}. In a
tree diagram the acts or actions are given after the initial fork as shown. As
shown in Figure 4.2, acts may be also be represented in the following matrix
form , i.e., either in row or column way.
Marketing Research Unit 4
Sikkim Manipal University Page No. 72
(Actions represented in rows) (Actions represented in cloumns)
Figure 4.2
States of Nature (Events): If the outcome of some action (or act) is not
known in advance, then that outcome is uncertain, but is vital for the choice
of any act. When there are many possible outcomes (or states of nature) of
an event, one cannot predict what will happen–it is only in terms of
probability that one may forecast.
The various states of nature are outside a firm and, as such, not under their
control, e.g., consumer demand, change of taste, improvement of
technology, etc. These affect the pay-off and, hence, the choice of an act. A
set of states of nature may be represented in any one of the following ways:
S = {S1, S2, S3, ....... Sn}
or E = {E1, E2, E3 .......En}
or = 1 2 3{ , , ...........}
Marketing Research Unit 4
Sikkim Manipal University Page No. 73
For example, if a cosmetic product is marketed, it may be highly liked by
customers (outcome 1 ) or it may not appeal at all (outcome 2 ), or it may
satisfy only a small fraction, say 20% (outcome 3 ).
1 2 3 = { , , }
In a tree diagram the places are text to acts. We may also get another act
on the happening of an event as shown in Figure 4.3.
Figure 4.3
Marketing Research Unit 4
Sikkim Manipal University Page No. 74
In matrix form they may be represented in either of the following two ways
as shown in Figure 4.4.
Figure 4.4
Outcomes
There is an outcome (or consequence) of the combination of each act with
each possible state of nature. This outcome is also known as conditional
value. In a tree diagram, outcomes are placed after events.
In general, if there are m possible actions and n admissible states of nature,
the consequences will be m × n in number.
It may be noted here that these consequences may be evaluated in several
ways such as
i) in terms of profit
ii) in terms of cost
iii) in terms of opportunity loss
iv) utility
Consequences of m × n in number are shown in Table 4.1 in centre cell in
row and column of a matrix.

Here outcome O21 means 2nd row and 1st column and Oij means ith row and
jth column and so on.

Assume yourself to be the head of an organization that is eyeing on
overseas expansions. What steps will you follow to zero down of the
right mode of entry? Illustrate it through suitable diagram.
Self Assessment Questions
13. The three components of decision-making are __________,
__________ and __________.
14. Decision-making problems deal with the selection of a single act from a
set of __________ acts.
4.8 Types of Decision Models
The aim of the decision theory is to guide the decision-maker in choosing
the best course of action. Depending upon the available information about
the occurrence of various states of nature and environment, the decision
models may be classified into the following types:
Decision-making under Certainty
Decision-making under Risk
4.8.1 Decision-making under certainty
In this case the decision-maker can easily select the course of action, as he
presumes that only one state of nature is relevant for his purposes. For
example, suppose a person desires to deposit Rs. 10,000 for a certain
period. Bank deposit gives 12%, Unit Trust of India offers 14% and
Government bond’s rate is 11% p.a. All the investments are fully secured.
Then surely investment in Unit Trust of India is the best choice.
4.8.2 Decision-making under risk
Here the decision-maker faces many states of nature. As such, he is
supposed to believe authentic information, knowledge, past experience or
happenings to enable him to allot probability values to the likelihood of
occurrence of each state of nature. Sometimes with reference to past
records, experience or information, probabilities to future events could be
Marketing Research Unit 4
Sikkim Manipal University Page No. 76
allotted. On the basis of probability distribution of the states of nature, one
may select the best course of action having the highest expected pay-off
value.
The expected value (or expected monetary value, i.e., EMV is widely used
to evaluate the alternative course of action or act). The expected value is
calculated by the following formula for one row only.
∑ Pj Oij = P1 Oi1 + P2 O12 + ............ + Pn Oin’
Where P1 to Pn indicate the probabilities of states of nature (or events) and
Oij the pay-offs of the outcomes due to combination of each event and act.
Activity 3:
Suppose the manufacturer of a particular brand of a desert cooler
decreased the price of his sets by 5%. It was observed that there
was an increase in sales during the succeeding four months as
compared to what the company had prior to price reduction. Has the
price reduction increased the sales? Justify your answer.
Self Assessment Questions
15. During decision-making under certainty, the decision-maker can easily
select the __________.
16. During decision-making under risk, the decision-maker has to _______
authentic information, knowledge, past experience or happenings.
4.9 Choosing a Good Research Design
Whatever may be the type of research work and studies, one thing that is
important is that they all meet on the common ground of scientific method
employed by them. One expects scientific research to satisfy the following
criteria:
The purpose of the research should be clearly defined and common
concepts be used.
The research procedure used should be described in sufficient detail in
permit another researcher to repeat the research for further
advancement, keeping the continuity of what has already attained.
The procedural design of the research should be carefully planned to
yield results that are as objectives as possible.
Marketing Research Unit 4
Sikkim Manipal University Page No. 77
The researcher should report with complete frankness, flaws in
procedural design and estimate their effect upon the findings.
The analysis of data should be sufficiently adequate to reveal its
significance and the methods of analysis used should be appropriate.
The validity and reliability of the data should be checked carefully.
Conclusions should be confined to those justified by the data of the
research and limited to those for which the data provided and adequate
basis.
Greater confidence in research is warranted if the researcher is
experienced, has a good reputation in research and is a person of
integrity.
In other words, you can say the qualities of a good research are:
Good research is systematic: it means that research is structured with
specified steps to be taken in a specified sequence in accordance with
the well defined set of rules. Systematic characteristic of the research
does not rule out creative thinking but it certainly does reject the use of
guessing and intuition in arriving at conclusions.
Good research is logical: This implies that research is guided by the
rules of logical reasoning and the logical process of induction and
deduction are of great value in carrying out research. Induction is the
process of reasoning from a part to the whole whereas deduction is the
process of reasoning from some premise to a conclusion which follows
from that very premise. In fact, logical reasoning makes research more
meaningful in the context of decision making.
Good research is empirical: It implies that research is related basically
to one or more aspects of a real situation and deals with concentrate
data that provides a basis for external validity to research results.
Good research is replicable: This characteristic allows research
results to be verified by replicating the study and thereby building a
sound basis for decisions.

17. The __________ design of the research should be carefully planned to
yield results that are as objectives as possible.
18. Conclusions should be confined to those __________ by the data of
the research.

4.10 Summary
This unit on research design gives an overiew of the research designs and
their application in marketing research. After discussing the meaning and
benefits of a research design, the discussion focusses on the four basic
types of designs namely exploratory, descriptive, quasi-experimental and
experimental. Causality, the relationship between data and conclusions,
forms the basis of this classification. The nature of causality and the need to
measure it has also been discussed.
The major design categories and their applications have been described.
Specific subtypes within the major categories have also been discussed.
Under the descriptive design, panel design, cross sectional design and
focus groups were discussed. The quasi-experimental designs discussed
include after only without control group, before-after without control group
the static group comparison, longitudinal design and multiple time series
designs.
Glossary
Research Process: The ordered set of activities focused on the systematic
collection of information using accepted methods of analysis as a basis for
drawing conclusions and making recommendations.
Data Collection: Systematic gathering of data for a particular purpose from
various sources, including questionnaires, interviews, observation, existing
records, and electronic devices. The process is usually preliminary to
statistical analysis of the data
Research Design: A plan outlining as to how information is to be gathered
for an assessment or evaluation that includes identifying the data gathering
method(s), the instruments to be used/created, how the instruments will be
administered, and how the information will be organized and analysed.
Experimental Design: A branch of statistics that attempts to outline the
way in which experiments should be carried out so the data gathered will
have statistical value.
Focus Group: A marketing research tool in which a small group of people
(typically eight to ten individuals engages in a roundtable discussion of
selected topics of interest in an informal setting.

Mini-case
Repatriate Co-op Bank is located in a town with a population of about 2
lakh. Its two main competitors were Bharat Co-operative Bank Textile
Workers Co-op Bank.
The size of all the three banks in terms of number of shareholders, assets,
were more are less the same. Interest offered on S.B and F.D were more or
less the same.
The main services offered by Repatriate Co-op Bank were savings bank,
vehicle and personal loan, mortgage loan, Jewel loan etc. The bank had an
ATM operating 24 hours. The services offered by other two banks were also
similar.
Since services offered by all the three banks were similar, the board of
directors of Repco Bank decided to find, loyalty of current customers to the
bank. The bank also wanted a measure of how customers perceive the
various services offered by the institution.
In the light of the above, the company appointed a leading market research
agency to conduct a survey among 2,000 current customers. The decision
of the bank was that, if this survey indicates anything worthwhile, a similar
survey would be conducted on current non-customers too.
The following was the specific information sought by the bank from the M.R
agency:
1. What percentage of the current bank customers of Repco Bank use the
services of competitors for one or more services?
2. For which service of the competitors does the current customer go?
3. Of the two competitors, who has the largest percentage of Repco Bank
customer as their customers as well?
4. How do the Repco Bank customers perceive the following attributes of
the bank?
a) Locational advantage
b) Quickness
c) Ambiance
d) Convenience of working hours
e) Courtesy of Staff
f) Correctness/Accuracy
g) Use of Technology
Marketing Research Unit 4
Sikkim Manipal University Page No. 81
h) How important is each of the above to Repco customers?
i) Do the above attributes have any relations with age, education, sex,
annual
j) income, numbers of years of association with Repco Bank?
A mail questionnaire has to be sent to the respondents of Repco Bank,
along with a covering note and reply envelope.
Question
What are the advantages of limiting of survey to just the current customers
of Repco Bank?
Hint: Base your answer on the facts like Surveys are relatively inexpensive,
useful in describing the characteristics of a population, can be administered
from remote locations (using mail, email or telephone) and so on.
