WHAT IS RESEARCH DESIGN?
It means:
 A framework or blueprint for
conducting marketing research
project.
 study used as a guide in collecting
and analysing data.
 A plan, structure and strategy of
investigation.
Major Components
 Data Collection Design
 Sampling Design
 Instrument Development and Pilot
Testing

RESEARCH DESIGN
Features / Components of a Research Design
 Define the information needed
 Design the exploratory, descriptive and / or causal phases of the
research
 Specify the measurement and scaling procedures
 Construct and pretest a questionnaire or an appropriate form of data
collection
 Specify the sampling process and sample size
 Develop a plan of data analysis

EXPLORATORY RESEARCH
Concepts
 Exploratory research studies are also termed
as Formulative research studies.
 The main purpose of such studies is that of
formulating a problem for more precise
investigation or of developing the working
hypotheses from an operational point of
view.
 Major emphasis is on the discovery of ideas
and insights.
Characteristics
 Flexible and versatile as formal research
protocols and procedures are not employed.
 Rarely involves structured questionnaires,
large samples, and probability sampling
plans.
7

EXPLORATORY RESEARCH DESIGNS
Objectives
 Formulate a problem or define a problem more
precisely
 Identify alternative courses of action
 Develop hypothesis
 Isolate key variables and relationships for further
examination
 Gain insights for developing an approach to the
problem
 Establish priorities for further research
8

EXPLORATORY RESEARCH DESIGN
METHODS
 Survey of concerning literature
 Studies of previous research, work already done, hypotheses already
tested
 Experience surveys
 Survey of people who have had practical experience with the problem to
be studied
 Idea is to obtain insight into the relationship between variables and new
ideas relating to the research problem
 Analysis of ‘insight-stimulating’ examples
 Particularly suitable in areas where there is little experience to serve as a
guide
 Intensive study of selected instances of the phenomenon of interest
 Examination of existing records and unstructured interviewing

Descriptive Research Design
11

DESCRIPTIVE RESEARCH DESIGN
 Objectives
 Describing the characteristics of relevant groups
 Estimating percentage of units in a specified population exhibiting a
certain behavior
 Determine the perceptions of product characteristics
 Determine the degree of association among marketing variables
 Making specific predictions
 Characteristics
 Assumes that the researcher has much prior knowledge about the
problem situation
 Hypothesis is formed prior to research
 Preplanned and structured
 Findings are conclusive
12

 Information needed
 Clearly defined
 Data Collection
 Through well defined surveys; Panels; Observational study; Examination
of records; Interviewing etc.
 Sampling
 Sample must be able to yield accurate information with a minimum
amount of research effort.
 Probability sampling is used
 Data Processing and Analysis
 Data must be examined for completeness, comprehensibility, consistency
and reliability
 Statistical operations on the data must be carried out
13

DESCRIPTIVE RESEARCH
CLASSIFICATION
 Cross-sectional
 Single: Information is collected from a given sample of population only
once
 Multiple: Information is drawn only once from two or more samples of
respondents
 Cohort: Series of surveys conducted at appropriate time intervals
 Longitudinal / Panel design
 A fixed population is measured repeatedly on the same variable
 The sample remains the same over time
14

Causal Research Design
15

CAUSAL RESEARCH DESIGNS
OBJECTIVES
 Objective
 To obtain evidence of cause-and-effect relationships
 To understand which variables are the cause and which variables are the
effect of a phenomena
 To determine the nature of the relationship between the causal variables
and the effect to be predicted
 Characteristics
 Requires procedure to reduce bias and increase reliability such as
manipulation of an independent variables in a relatively controlled
environment (An environment where other variables that may effect the
dependent variable are controlled or checked as much as possible).
 Main method is experimentation.
16

CAUSAL RESEARCH DESIGNS
METHOD
 Information needed
 Clearly defined in the form of a hypothesis
 Data Collection
 Through experimentation, causal surveys.
 Sampling
 Sample must be able to yield accurate information with a minimum
amount of research effort
 Statistical controls are used
 Probability sampling is used
 Data Processing and Analysis
 Using advanced statistical analysis tools

COMPARISON OF VARIOUS RESEARCH DESIGNS
 Exploratory vs Conclusive
 Exploratory, Descriptive and Causal Research Designs

COMPARISON OF BASIC RESEARCH DESIGNS
20

Causal research
Research design
in which the
major emphasis
is on determining
cause-and-eﬀ ect
relationship
Exploratory
research
Design in which the
major emphasis is
on gaining ideas and
insights
Descriptive research
design are used to
describe the
characterstics of
certain groups such
as customers age
group, gender etc.
