Question

Quizplus · Accepted Answer

Self-selection bias occurs when individuals or groups are more likely to participate in a study or survey due to their own preferences, experiences, or other factors that may not be representative of the entire population. This can skew the results and make them less accurate or not applicable to the general population. Thus, self-selection bias leads to samples that are not representative of the entire population, as described in option A. Option B and C are incorrect as self-selection bias does not improve estimators or increase the accuracy of test results. Option D is also incorrect as self-selection bias does have an effect on empirical estimation.
