Question

Quizplus · Accepted Answer

Non-response bias occurs when those who choose to respond to a mail survey are not representative of the general population. This skews the results and makes it difficult to generalize findings to the population as a whole. Option A and B also describe potential issues with mail surveys but do not specifically relate to non-response bias. Option D refers to a different type of bias (self-selection bias) that can occur if attempts to increase response rates only attract certain types of individuals to participate in the survey.
