8.2: Face-to-Face

  • Page ID
  • Trained interviewers meet individually with the survey respondents and ask them the survey questions in person

    • Advantages:


    • longer and more complex questions can be accommodated


    • questions that require the respondent to react to visual images can be asked



    • labor costs for interviewer training is high


    • transportation costs for interviewers’ travel to and from the respondents’ locations are very high


    • respondents are less and less likely to allow strangers into their homes so the completion rate is low


    Evaluating face-to-face survey data: The following questions are important guides to determining the quality of the firm doing the survey and to the reliability of the information gathered by the survey:

    • How were the interviewers selected?


    • Were the interviewers chosen to avoid the bias of race, age, sex or other social factors that might limit respondents’ comfort level in participating?


    • How was the work of each interviewer checked?


    • What instructions did the interviewers receive regarding the selection of respondents?
