Thus, make the interviewer able to read the respondents body languages and able to know the emotions of the respondents towards certain questions by the tone of voice that the respondents using.

Another advantage of using an interviewer to ask the questions in a social survey is the answers that the respondents give will be more reliable because when the respondents missunderstood the questions or the answer that the respondents gave does not related to the questions, the interviewer might able to explain his/her questions actually is and explain the questions thoroughly.

One disadvantage of using interviewer to ask the questions in a social survey is the present of bias. Since, the interviewer are able to explain the questions it might force or influence the respondents to answers the questions that the interviewer wants. For example : when the respondents does not really understand the questions the interviewer will starts to explain more about the questions and give some example of the answers. When the respondents still doesn not understand, he/she will take the interviewer answers as their answers which is not reliable and not valid.
