This document discusses research methodology, specifically focusing on methods for collecting primary and secondary data. It defines primary data as original data collected by the researcher, while secondary data is already existing data collected by others. Some key methods for collecting primary data discussed include direct personal observation, indirect oral interviews, collecting information through agencies, mailed questionnaires, and using enumerators to distribute schedules. Sources of secondary data include government publications, research institutions, commercial/financial institutions, and unpublished records. The document also covers case study methodology, defining it as an intensive examination of a single unit or case and outlining its characteristics and limitations.
This ppt attempts to introduce the concept of research methodology to the pre-service student teachers. Hence, it does not deal with every minute aspect of research methodology, but is delimited to basics.
It describes the types of research, differences between quantitative and qualitative research and gives an introduction to Participatory Rural Appraisal tools

Information is unbiased.
Adequate information can be had.
Information is collected from different
parties.
All the aspects of the problem can be
ascertained.

Interview with an improper man will
spoil the results.
To get real position, a sufficient
number of persons are to be
interviewed.
Careless attitude of the informant will
affect the degree of accuracy.
Witnesses may colour the information
as per their interests.

and tastes.
Adopted by newspapers, periodicals,
agencies etc.,

obtained at regular intervals from a
wide area.

Speedy information is possible
Useful where information is needed
regularly
18. Demerits of ITA
Information may be biased
Degree of accuracy can not be
maintained
Uniformity cannot be maintained
Data may not be original
19. 4. Mailed questionnaires.
Questionnaire consisting of a list of
questions.
There are blank spaces for answers.
This questionnaire is sent to the
respondents.
20. Suitability
Where informants are spread over a
wide area.
Where there could be a legal
compulsion to supply information.
21. Merits of MQ
Most economical of all other methods.
Widely used when the area of
investigation is large.
Saves money, labour, time.
Error will be very small.
22. Demerits of MQ
No direct contact to respondents may
lead low degree of accuracy and
reliability of the data. Suitable only for
literate people.
Delay in receiving duly filled in
questionnaires.
People may not give the correct
answer.
The questionnaire is inelastic.
Informants may not be willing to give
written answers.
23. 5. Schedules sent through
enumerators
A number of enumerators are selected
and trained to filling up schedules.
The investigator goes to the
informants and collect data.
24. Suitability of SSTE
Useful for public organisations and
research institutions.
Where requires personal contact.
25. Merits of SSTE
Very useful in extensive enquiries.
Yields reliable and accurate results.
Scope of the enquiry can also be
enlarged.
Useful, even the respondents are
illiterate.
Less chance of non-response.
26. Demerits of SSTE
Very Costly method( Training and Pay)
Time consuming.
Chance of personal bias may lead
false conclusion.
Quality of data depends upon the
personal qualities of the enumerator.
Not suited to all persons
27. Secondary Data
Already collected by someone for
some purpose and are available for
the present study.
28. Sources of Secondary Data
Sources of secondary data can be
divided into two:
1. Published Sources
2. Unpublished Sources
29. Published Sources
Various governmental, international
and local agencies publish statistical
data.
The following are some important
sources:
(a) International Sources:
Reports by international agencies and
bodies on economic and statistical
matters .
Ex: IMF, IBRD, ILO, UNO, ADB……
30. b. Official publications of Central and
State Governments:
Reports by Union and State
governments on a number of subjects.
Ex: RBI Bulletin, Census of India,
Statistical Abstracts of states,
Agricultural Statistics of India, etc…
32. d. Publications of Research Institutions:
Publications of research findings by
research institutions.
Ex: Indian Statistical Institutions(ISI),
Indian Council of Agricultural
Research(ICAR), Indian Agricultural
Statistics Research Institute(IASRI),
CDS, MIDS, etc…
33. e. Publications of Commercial and
Financial Institutions:
Ex: Centre for Monitoring Indian
Economy(CMIE), Commercial Banks,
Insurance Agents, etc….
34. f. Reports of various committees and
commissions appointed by the
government:
Ex: Wanchoo Commission – Taxation
Pay Commission Reports
Land Reforms Committee Reports etc…
35. g. Journals and Newspapers:
Current and important materials on
statistics and socio-economic
problems.
Ex: Tamil News Papers, Economic
Times, The Hindu, etc…
36. 2. Unpublished Sources
Records maintained by various govt.
and private offices.
Researches carried out by individual
research scholars in the universities or
research institutes.
37. Precautions(Challenges) in the
use of Secondary Data
a) Suitability of data
b) Adequacy of data
c) Reliability of data
d) Old Data
e) Aggregation of Data in inappropriate
unit
38. Case Study Method
Meaning:
Case Study refers to the intensive
investigation of a particular unit.
‘The Social Microscope’ – Burgess
Definitions:
“A comprehensive study of a social unit, be
that unit a person, a group, a social
institution, a district or a community is called
a case study”
– Pauline V.Young
39. Characteristics of the CSM
1. Single Unit Analysis:
One single unit (a person, family, institution or
community) may be studied.
Ex: Study of a particular bank.
2. Intensive Study:
Covers a long period of time and study
intensively.
(5 to 10 years for historical evolution)
40. 3. Integrated Study:
A social unit always has complex
phenomena.
Complete study is needed to cover all facts of
a social unit.
4.Qualitative Analysis:
It does not just collect information, gives a
clear insight into life.
(No. of crime Vs Reasons for crime)
41. 5. Interrelationship can be studied:
Mutual relationship of casual factors take into
consideration.
Social Factors can act and react upon each
other.
6.Behaviour Pattern can be studied:
Since case study method is qualitative in nature, it
can study the reasons for change in behavior.
42. 7. It helps to generalize social science.
8. Flexible method:
Researcher has complete freedom to change
or omit or distort the variables.
9. Complementary Study:
Stresses the need of complementary study
for getting proper solution to the problems.
43. Limitations of CSM
1. Develops Overconfidence.
2. False generalisation
3. Doesn’t provide universal aspects of
a phenomena
4. Consumes more Time, Money and
Man-power.
5. Unscientific and invariable method.
44. 6. Difficult to apply
7. Seldom comparable
8. Scope for errors
9.Objectivity lost
10. Not useful for quantitative studies
11.Unrealistic assumptions
45. Assumptions of Case-Study
Method
Uniformity of human nature
Natural history of the unit
Comprehensive study
