Advantages: It has a higher expected response rate than other methods of data collection. In addition, there will probably be fewer incorrect responses resulting from respondents misunderstanding some questions, because the interviewer, if asked, can clarify misunderstandings.

Disadvantages: It has the potential for bias if the interviewer says too much whenever asked to clarify misunderstandings of some questions. The main disadvantage of personal interviews is that they are expensive, especially when travel is involved.
