Question

Quizplus · Accepted Answer

Non-response bias occurs when individuals who choose not to participate in a survey differ from those who do participate in some systematic way that affects the results of the survey. Therefore, a researcher should be particularly worried about non-response bias when there is non-response to the survey. The size of the sample or the design effect may also be important factors, but they do not directly relate to the concern about non-response bias.
