Question

Write short note on collection of data

Answer 1

The data collected may be :
(A) Primary Data
(B) Secondary Data

(A) Primary Data : Primary data is the data which is collected by the investigator for the first time.

It includes the following types:

1) Direct Personal Investigation- when researcher conducts experiment or survey and collects data himself/herself.

2) Indirect Oral Investigation- this may be done by researcher collecting data through a telephone or hiring an Investigator to do it for him/her.

3) Questionnaire Method- when required data is obtained by sending a questionnaire to selected people. This can be done by Post or sending an Ennumerator to collect the answers and record them.

(B) Secondary Data : When the investigator himself does not make any investigation, but he uses the data which has been collected by someone else, then such data is known as secondary data. He/She can get such data from published or unpublished sources. They do not have to put in much effort for data collection and thus save time, money and energy.
