Quizplus · Accepted Answer

Personal interviews are the most costly form of data collection as they involve hiring interviewers, providing transportation and logistics, and paying incentives or compensation to the respondents. Telephone interviews, mail surveys, fax surveys, and email surveys are relatively less costly as they do not involve face-to-face interaction and can be done remotely. However, personal interviews provide richer and more detailed data and allow for better rapport building with the respondents. The choice of data collection method should depend on the research objectives, sample size, budget, and time constraints.
