INTERVIEWER BIAS

Statistics Directorate    
French Equivalent: Biais lié à l'enquêteur

Definition:
In surveys of human populations by interview, bias in responses or recorded information which is the direct result of the action of the interviewer. This bias may be due, among other things, to failure to contact the right person(s); to the failure of the interviewer to establish proper relations with the informant, with the result that imperfect or inaccurate information is offered; or to systematic errors in recording the answers received from the respondent.
