A police department commissioned a door-to-door survey of citizens on whether they commit minor law infractions, such as speedin
g or illegal parking. The interviewers told the interviewees that they would not be investigated or ticketed for any minor infractions they may have committed. An analysis suggested that there was bias in their responses.This would likely be an example of a (an):_________ a) Placebo effect
b) Interviewer-induced bias
c) Under-coverage bias
d) Voluntary response bias
e) Double-blind effect
The example given in the question illustrates the Interviewer-induced bias. This occurs when the situation created by the interviewer is such that the respondent will have to give the kind f answer that the interviewer wants to hear.
For example, in the question, we can deduce that the interviewers told the interviewees that they won't be investigated and the gave bias replies based on that.
