WHAT IS COMMON ?
UNCERTAINTY
CAN IT BE ELIMINATED ?
CAN IT BE REDUCED ?
RESEARCH REDUCES UNCERTAINTY.
RESEARCH
All
of us have done research
knowingly or unknowingly !!
RESEARCH
IS A SYSTEMATIC
SEARCH FOR INFORMATION.
RESEARCH IS A PURPOSEFUL
INVESTIGATION.
RESEARCH :
FOUNTAIN OF KNOWLEDGE
TO FIND HIDDEN TRUTH
TO DISCOVER ANSWERS TO QUESTIONS
SIGNIFICANCE OF RESEARCH
Research leads to invention.
Helps in solving operational problems.
Provides the basis for govt. policies.
Helps in solving social problems.
Helps in taking decisions.
RESEARCH & COMMON SENSE
Systematic
Objective
Reproducible
Relevant
Research is not a fishing expedition.
OBJECTIVES :
To gain familiarity with a phenomenon or to
achieve new insights into it .
(Exploratory or formulative research studies)
To find out / portray accurately the
characteristics of a particular
individual, situation or a group.
(Descriptive research studies)
To determine the frequency with which
something occurs or with which it is
associated with something else.
(Diagnostic research studies)
To test a hypothesis of a causal relationship
between variables.
(Hypothesis testing research studies)
TYPES OF RESEARCH :
EXPLORATORY RESEARCH :
1)The literature survey
2)The experience survey
3)The analysis of case studies
CONCLUSIVE RESEARCH :
1)
Descriptive research
2) Experimental research
CLASSIFICATION OF RESEARCH :
Applied Vs. Fundamental research
Descriptive Vs. Analytical research
Quantitative Vs. Qualitative research
Conceptual Vs. Empirical research
ROLE OF
RESEARCH IN
IMPORTANT AREAS
MARKETING :
Consumer buying behavior
Demand forecasting
Measuring advertising effectiveness
Media selection
Product positioning
New product potential
PRODUCTION :
What to produce?
How much to produce?
Plant location
Production process
Quality process
Optimum inventory level

RESEARCH METHOD
Methods of data collection
Statistical methods for study of
relationship
Methods used to evaluate accuracy
of the results obtained
RESEARCH METHODOLOGY
A way/process to systematically
solve the research problem
Cover various steps adopted by the
researcher
Methodology will be different from
problem to problem
CRITERIA OF GOOD RESEARCH
The purpose of the research should be clearly
defined.
The research procedure used should be
described in sufficient detail.
The design of research should be properly
planned.
Validity and reliability of data should be
checked carefully.
Cont..
Method
of analysis should be
appropriate and analysis of data should
be adequate.
Conclusion
should be confined to
those justified to data.
Researcher
should have knowledge,
experience and integrity.
PROCESS OF RESEARCH
Problem definition
Research design
Data collection
Data analysis
Interpretation of results
R.L.ACKOFF: Five Component of
a Problem
Research - Consumer
Research - Consumer’s objectives
Alternative means to meet the objectives
Doubt in regard to select of objectives
One or more environment to which the problem
pertains
MERTON: Three components in
the promulgation of a problem
The originating question: What
Rationale of question: Why
The specifying question: Possible answer
DEFINING A PROBLEM: Steps
Statement of the problem in a general way
Understanding the nature of the problem
Surveying the available literature
Developing the ideas through discussion
Rephrasing the research problem into
working proposition
A COMPLETE PROBLEM DEFINITION
Specify the following:
Unit of analysis: Source of information “on
what”, “on whom”.
Time and space co-ordinates.
Characteristics of interest: 2 x 2 matrix by
Frank, Massy & Wind.
Environmental condition:
Beyond control
Within control

RESEARCH PROBLEM AS
HYPOTHESIS TESTING
It is often convenient to structure a research problem
in term hypothesis to be tested.
Hypothesis is simply a statement about the Universe :
It may or may not be true.
The research is designed to find out the truth.
Hypothesis guides the researcher to select the
relevant information
SOURCES OF HYPOTHESIS
Personal experience and observations.
Hypothesis may rest on the finding of
other studies.
Hypothesis may stem from a body of
theory.
CHARACTERISTICS OF A
USEABLE HYPOTHESIS
It should be empirically tested.
It should be closest to thing observable.
It must be conceptually clear.
It must be specific.
RESEARCH DESIGN
A blue
print for the research study .
Covers
various phases of research.
A comprehensive
master plan
Guiding framework for the research study.
RESEARCH DESIGN DECISIONS
ARE:
What is the study about ?
Why is the study being made?
Where will the study be carried out?
What type of data required ?
Where the required data is found?
What periods of time will the study
include?
Cont..
What
will be the sample design?
What techniques of data collection will be
used?
How will be the data analyzed?
In what style will the report are prepared?
FOUR PHASES OF
RESEARCH DESIGN
Sampling
design: Methods of selecting items
Observational design: Conditions on which the
observations are to be made.
Statistical design: How the data to be
analyzed?
Operational design: procedures to be carried
out.
IMPORTANT CONCEPTS
Dependent
& Independent variable.
Extraneous Variable : independent variable not
related to the purpose of the study.
Control : effect of extraneous variable is
minimum .
Research hypothesis.
CAUSALITY
– outcome
Causal Variable - Effect Variable
There is strong evidence to say that there
exists a strong association.
The action must precede outcome.
Action
There
is strong evidence to say that there were
no other possible factors, which could have
resulted in the observed outcome.
RESEARCH DESIGN FOR
EXPLORATORY RESEARCH STUDIES
The survey of literature
The experience survey
The analysis of selected cases.
Design is flexible.
No structured questions
Convenience sampling.
RESEARCH DESIGN FOR DESCRIPTIVE
RESEARCH STUDIES
Panel
Research Design : Periodic
information collection from a sample of
respondents.
Cross Sectional Design : Picture of a
situation at a give point of time.
Focus Groups for free flowing discussions.
RESEARCH DESIGN FOR

STRUCTURED QUESTIONNAIRE
Questions & answers are specified.
Comments in the respondent’s own words
are held to a minimum.
Usually has fixed alternative answers to
each question.
Simple to administer & to analyse.
Considered inappropriate for study on
attitude & feelings.
UNSTRUCTURED QUESTIONAIRE
Useful
for in-depth interviewer
More open-ended questions
Employed in pre-testing and for
constructing structured questionnaire.
DESIGNING A QUESTIONNAIRE
Covering
letter: for mailing
- should be short and simple
The question sequence:
To be arranged logically
Personal questions: Ask towards the end
Difficult questions: Strain on memory and
intellect: ask towards the end.
QUESTIONNAIRE
The
question wording: an art
Should be simple and easy to understood
Ambiguous questions should be avoided
Type
of questions:
multiple choice / Y/N / open -ended

body of information about a system
gathered for the purpose of studying the system

of variables and their interrelationship
