In a short essay, list and discuss the three categories of personal interviewing methods

What will be an ideal response?

a. Personal in-home interviews - in this type of interview, respondents are interviewed face-to-face in their homes. The interviewer's task is to contact the respondents, ask the questions, and record the responses. In recent years, the use of personal in-home interviews has declined. Nevertheless, they are still used, particularly by syndicated firms.
b. Mall intercept personal interviews - in this type of interview, respondents are intercepted in shopping malls. The process involves stopping the shoppers, screening them for appropriateness, and either administering the survey on the spot or inviting them to a research facility located in the mall to complete the interview.
c. Computer-assisted personal interviewing - in this type of interview, the respondent sits in front of a computer terminal and answers a questionnaire on the screen by using the keyboard or a mouse. This method has been classified as a personal interview technique since an interviewer is usually present to serve as a host and to guide the respondent as needed.
