Dear student,
Direct personal investigation is a method of collecting primary data. In this the investigator himself collects information from the respondents. The investigator must be skilled, tactful and unbiased to collect data.
This method of collecting data offers various benefits like:
* The data collected by this method is original, accurate, reliable and uniform.
* This method allows flexibility as investigator personally collects data.
* The investigator can choose the language of communication according to the knowledge and comfort level of the informant.
This method suffers from following demerits:
* It is an expensive and time consuming method.
* The data may lack reliability and uniformity if investigator is biased and not properly trained.
* It is a lengthy method and not suitable if field of enquiry is wide.
Regards
