Primary Data Collection Methods

Primary data collection refers to the process of gathering firsthand information directly from the source. There are various methods of primary data collection, including direct personal investigation, indirect oral investigation, and telephone interviews. Each method has its advantages and limitations, and the investigator can make necessary adjustments in his set of questions in some of these methods.

1. Direct Personal Investigation
In direct personal investigation, the researcher interacts face-to-face with the respondents to collect data. This method allows for a high level of control and flexibility in the data collection process. The investigator can make necessary adjustments in his set of questions during the interview based on the respondent's responses. If certain questions are not clear or if additional information is required, the investigator can clarify or probe further to gather more accurate and detailed data. This method provides an opportunity for the researcher to adapt the questions according to the context, respondent's understanding, and specific requirements of the study.

2. Indirect Oral Investigation
Indirect oral investigation involves gathering data through intermediaries such as local leaders, opinion leaders, or community representatives. In this method, the investigator does not have direct contact with the respondents. However, the investigator can still make necessary adjustments in his set of questions by providing guidelines or instructions to the intermediaries. The intermediaries can act as facilitators, ensuring that the questions are asked correctly and that the respondents' answers are accurately recorded. If any issues or discrepancies arise, the investigator can communicate with the intermediaries to make the necessary adjustments in the data collection process.

3. Telephone Interviews
Telephone interviews involve conducting interviews over the phone. While this method may not provide the same level of flexibility as direct personal investigation, the investigator can still make necessary adjustments in his set of questions during the interview. If certain questions are not understood by the respondents or if further clarification is required, the investigator can modify the questions or provide additional explanations over the phone. However, it is important to note that the scope for adjustments may be limited compared to face-to-face interactions.

Conclusion
In summary, the investigator can make necessary adjustments in his set of questions in methods such as direct personal investigation, indirect oral investigation, and telephone interviews. These methods provide opportunities for the researcher to adapt the questions according to the context, respondent's understanding, and specific requirements of the study. Adjustments in the set of questions help in obtaining more accurate and relevant primary data for analysis and research purposes.
