2. What is Research?
Research is a systematic and scientific search for new facts or ideas
in any branch of knowledge --
to find something new
to establish well believed thoughts and facts
Research is a systematic method of defining a problem, formulating a
hypothesis, collecting the facts or data, analyzing the facts and
reaching certain conclusions either in the form of solutions of the
problem or generalization of some theoretical formula.
Search for knowledge
Scientific investigation
Gaining New Knowledge
Visiting Known to Unknown world
3. Objectives of Research-----------------
1) To gain familiarity with a phenomenon or to get new insight into it
2) To portray accurately the character of an individual or an object or
situation or a group
3) To determine the intensity of matters through frequency which is
associated with something else
4) To test the hypothesis of casual relationship between the variables
1) Null Hypothesis
2) Alternative Hypothesis
5) To relate findings to managerial decisions:
Policies, objectives are interactive elements and feedbacks are necessary in
decision making
Problem must be described and the decision must be given
Managers must know how to solve problems
Given the alternatives, managers must narrow down to most possible
course of action.
4. Why is Research Necessary?

9. Criteria of Good Research
The purpose of research should be clearly defined
The research procedures should be described in detail so that other
researcher can repeat the research for further advancement, keeping the
continuity of what has already been done
Research design should be carefully planned to yield objective results
The procedural limitation should be mentioned
The analysis of data should be sufficiently adequate to reveal its
significance and methods of analysis should be appropriate
The validity and reliability of data should be checked carefully. Validity
must be measured what it is suppose to measure. Reliability is
consistency of results in repeated studies
Conclusion should be based only on collected information
It’s presentation should be logical and systematic
Should be empirical and replicable
10. Steps in Good Research
Defining the problem
Identifying data needs and research design
Communication methods (that will be applied for collecting data)
Source of data and sampling procedure : sampling plan from
which data to be collected
Data gathering and processing
Analysis and interpretation
Presentation and flow through with findings
11. Defining Research Problem
Research problem refers to the difficulty that a researcher
experiences in the context of theoretical or practical
situation and wants to obtain a solution for it
12. Defining the Research Problem: Conditions
1. There must be an individual or a group that has some problem
2. There must be some objectives to be attained
3. There must be alternative means of attaining the objectives
4. There must remain some doubt in the mind of the researcher
regarding the alternatives
5. There must be some environment to which the difficulty pertains.
13. Techniques involved in defining Problem
1. Statement of the problem in a general way
2. Understanding the nature of the problem
3. Surveying the available literature
4. Developing the idea through discussion
5. Rephrasing the research problem
14.
15. What is Research Design
A research design is the pattern of an outline of a research
projects workings. It is a statement of only the essential elements
of a study that will provide the basic guidelines for the details of
the project.
It comprises a series of prior decisions that taken together to
provide a master plan.

18. Types of Research Design
1. The Sample Design
2. Observational Design (Condition under which
observation are to be made)
3. Statistical Design (How many times are to be
observed ad how data are analyzed)
4. Operational Design (How the procedure that has
been specified in the above should be carried out)
19. Important Features of a Research Design
1. It must include a plan :
The plan will specify the sources and types of information
relevant to the research problem
2. It must include a Strategy :
It will specify that the approach can be used for gathering
and analyzing data.
3. It must include the time and cost budget :
Time and cost budget must be included since most studies
are done under these constraints.
20. Factors that must be considered for Research Development
1. The objectives of the problems to be studied
2. The nature of the problem to be studied
3. The availability and skills of the researcher and his staff
4. The means of obtaining the information
5. The availability of time and money for the research work
21. Benefits of a research Design …………………………………….
1. It serves as bridge between research objectives
and course of action to be taken to attain
objectives
2. It works as research light of research work :
May have foggy notions
All things cannot be memorized
Sequence of action may be disrupted
3. It provides specific details of research works:
What data are needed
Whether there is any confusion irrelevancy in data or findings
4. It provides linkage between expectations and
findings of the study (on the basis of hypothesis)

3. To decide the sampling frame (source list)
4. To decide the size of sample
5. To decide the parameters of interests
6. To decide the budgetary constraints
7. To decide the specific sampling procedures
26. Types of Sampling Design
1. Purposive or biased sampling
2. Probability or random sampling
I. Pure Random Sampling

b) Cluster Sampling
c) Multi-stage sampling
d) Systematic sampling
27. How to reduce it:
1. To keep sample survey as easy to execute as
possible
2. To use smallest sample size consistent with the
objectives of the study.
3. To restrict the questionnaire to data that are
essential to the main issue
4. To pretest the questionnaire
5. To make sure that no question is asked to the
respondent that s/he cannot answer
