3. Need of Data Collection
Why is Data Collection Needed ?
•To get information for analysis.
•To get idea about real time situation.
•For comparison between two situation.

4. Factors to be considered before
collection of Data
Primary & Secondary sources of Data: By Ajay Anoj & Gokul
•Object and scope of the enquiry.
•Sources of information.
•Quantitative expression.
•Techniques of data collection.
•Unit of collection.

5. Sources of Data
Primary & Secondary sources of Data: By Ajay Anoj & Gokul

6. Internal and External Source of
Data
Many institutions and
departments have information
about their regular functions,
for their own internal purpose.
When those information is
used in any survey, it’s called
Internal Source Of Collection
of Data.
E.g.., Railway Educational
Institutes & Social Welfare
Societies etc.
When information is
collected form outside
agencies, it is called
external source of data.
Such type of data are
either Primary or
Secondary.
This type of information
can be collected by
Census or Sampling
method by conducting
surveys.

7. Primary Data
Primary & Secondary sources of Data: By Ajay Anoj & Gokul
•Primary data are those which are collected for
the first time.
•It is real time data which are collected by the
researcher himself.
•This is the process of Collecting and making use
of the data.
•This Data originated by the researcher
specifically to address the research problem.

8. Primary Research methods
Primary & Secondary sources of Data: By Ajay Anoj & Gokul
Focus Groups –bring together respondents with common
characteristics
Observation-actually view respondents
Experiment-controlled variables and respondent groups.
Non-personal survey–on site, telephone, mail, fax, computer,
panel
Personal interview -one-on-one survey with respondents
Official records –internal document survey research

9. Method of Collecting Primary Data
Primary & Secondary sources of Data: By Ajay Anoj & Gokul
1. Direct personal Investigation ( i.e. Interview Method)
Under this method the investigator collects the data
personally. He approaches the objects, conducts the enquiry
on the spot, collects information and does the needful. For
the successful collection of data under this method, it’s
necessary that the investigator should be polite, unbiased
and ware of the local conditions, environment and languages.

10. Method of Collecting Primary
Data
Primary & Secondary sources of Data: By Ajay Anoj & Gokul
2. Indirect oral investigation ( i.e. through enumerators)
Under this the investigator doesn’t collects the information
directly, instead he gets them indirectly through those
persons who know the information and who are ready to part
away with the information they posses. This method is used
in case where direct contact is not possible.
3. Investigation through Local reporters Questionnaire
In this method data are not collected through specially
appointed agents/ correspondents/investigators/enumerators
but local agents or correspondents are requested to collect
the information. They collect the information in their own
fashion and according to their liking’s and disliking.

11. Method of Collecting Primary
Data

4. Investigation through mailed
Questionnaire
Under this method the investigator may either
appoint local agents/ investigators/
enumerators and mail them the questionnaire
for collecting information or collecting by his
own using mail or telephone.

Data

5. Investigation through Observation
In this watching behavior of object and most commonly used
method in behavior science. One major problem in this
method is that Natural response is not obtained when
respondent know he is observed.
Type of Observation-
1)Participant Observation
2)Non-Participant Observation
3)Disguised Observation
4)Controlled Observation
5)Uncontrolled Observation

13. Traditional data collection
methods
Primary & Secondary sources of Data: By Ajay Anoj & Gokul
Mailingpaper questionnaires to respondents,
who fill them out and mail them back
Having interviewers call to respondents on the
telephoneand ask them the question in a
telephone interview
Sending the interviewers to the respondent’s
home or office to administer the questions in face-
to-face(FTF) interviews

15. Important characteristics of good
questionnaires
Plan a user-friendly format
Gather demographic data –age, gender, etc.,
when necessary.
Avoid ambiguity
Ensure ease of tabulation
Develop for completeness –get all the data
Pilot test the instrument

16. Non sensitive questions about behavior Provide
memory help
Uses aided recall
(or ask separate questions about subcategories)
Please look cerefully at the
following list of volountary
organisations: which, if any,
do you belong to?
AReligious organisations
BCultural organisations
CPolitical groups
DOther
To which
volountary
organisation do
you belong to?
Primary & Secondary sources of Data: By Ajay Anoj & Gokul

17. Non sensitive questions about behavior Pay
attention to the wording
 Are you:
Married
Divorced
Widowed
Separated
Never married
With closed questions, include all reasonable
possibilities as explicit response options
Are you:
•Married
•Single

19. Secondary Data
Primary & Secondary sources of Data: By Ajay Anoj & Gokul
•Secondary data are those that have already been
collected by others.
•These are usually in journals, periodicals, dailies,
research publications, official records etc.
•Secondary data may be available in the published or
unpublished form. When it is not possible to collect
the data by primary method, the investigator go for
Secondary method.
•This Data collected for some purpose other than the
problem at hand.

20. Method of Collecting Secondary
Data
Primary & Secondary sources of Data: By Ajay Anoj& Gokul
1. Published Sources
a) International Publication
UNO publishes a number of journals and periodicals which are best sources
of secondary data for national as well as international facts.
b) Government Publications
The Govt. of India as well as other state Govt. publish data for their use as
well as for the use of researcher and others. These data are very much
accurate and reliable for various types of investigations.
c) Publication
Municipal corporations, boards, etc. publish data pertaining to birth rate,
death rate, literacy, etc. These can be effectively put to use by
investigators.
d) Commercials Research, Educational Institute, Unions, Organizations
etc. These institutions also conduct enquiry and publish their reports
through which data can be had for use of investigators enquiring on the
related subjects.

21. Method of Collecting Secondary
Data

2. Unpublished Sources
In some of the cases, enquiry are conducted,
data are classified and analysed but due to
some reasons or other findings are published
though they are preserved either by the
individual or a society. They can also be used
by the investigators as Secondary Data.

22. Examples of Primary& Secondary
data
 Data and Original Research
 Diaries and Journals
 Speeches and Interviews
 Letters and Memos
 Autobiographies and Memoirs
 Government Documents
 Census Statistics
 Encyclopaedias
 Chronologies
 Biographies
 Monographs (a specialized book or article)
 Most journal articles (unless written at the time of
the event
 Abstracts of articles
 Paraphrased quotations

23. Difference between Primary and Secondary Data
Real time data.
Sure about sources of data.
Help to give results/finding.
Costly and Time consuming
process.
Avoid biasness of response
data.
More flexible.
Past data.
Not sure about sources of data.
Refining the problem.
Cheap and No time consuming
process.
Can not know if data biasness or
not.
Less Flexible.

24. Selection of an appropriate data
collection method
The researcher must judiciously select the
method/methods for his own study, keeping in
view the following factors:

26. Triangulation of data
Definition: The collection and use of similar and related data from
different sources using different tools
Supplements incomplete data sources
Eliminates bias
Possible to assess the balance of evidence regarding
each source
A Check on sources and informants with incentives to
mislead.
Primary & Secondary sources of Data: By Ajay Anoj & Gokul

27. IMPORTANT
Remember: each method of data collection has
its use and none is superior in all
situations
Desirable: selection of method depends on the
nature of a particular problem in
consideration of time and resources.
Required: Experience and ability of the
researcher.
