Q6. what are various methods of collecting primary data? Explain any one method along with it marits and demerits
Answers
Answer:
Primary data can be collected in a number of ways. However, the most common techniques are self-administered surveys, interviews, field observation, and experiments. Primary data collection is quite expensive and time consuming compared to secondary data collection.
Explanation:
The following are the different methods of collecting primary data:
1. Direct Personal Interview
The researcher contacts the respondents personally and obtains all the relevant information for his study.
2. Indirect Oral Interview
This approach is used when it is not possible to get the information directly from the parties concerned.
For example, if the study is on addiction to alcohol, the required information can be better secured by approaching those who are closely related to the addict.
3. Information from correspondents
In this case, the investigator will appoint agents or correspondents to collect the necessary information from the parties. Newspaper agencies follow this approach.
4. Mailed Questionnaire Method
Here, the investigator will prepare a questionnaire, containing the questions pertaining to the study, and send it to each respondent by post. The respondent will fill it and send it back to the investigator.
5. Schedules sent through enumerators
In this method, the researcher would send schedules through enumerators or interviewers. The interviewers would interview the respondents and record the details.
The main difference between a questionnaire and a schedule is that the former is filled up by the respondents in their own handwriting and sent back to the investigator by post while the latter is filled up by the interviewers in the presence of the respondents.
