The Role of Interviewers

Make Quality a Priority

Interview Correct Respondents

Always interview the person selected; this is the only way to ensure that the sample is random.

Often the person selected is hard to reach or isn't home when you call, and the person who answers the telephone suggests you simply conduct the interview with him or her instead. Don't be tempted by this “easy complete.” Instead say something like, “No, I'm sorry. I have to interview the respondent that was selected randomly. The statistical accuracy of the study depends on it.”
