A problem with nonprobability samples is
A)they are always more representative than probability samples.
B)one cannot assess the amount of sampling error likely to occur.
C)there is no problem with using nonprobability samples
D)All of these are correct.
E)None of these are correct.

Question

Quizplus · Accepted Answer

Nonprobability samples do not have a known probability of selection, which makes it difficult or impossible to calculate sampling error. Therefore, there is no way to know how representative the sample is of the population, which is a major problem with nonprobability sampling. Option A and C are incorrect as nonprobability samples are generally less representative than probability samples. Option D and E are incorrect as Option D implies that nonprobability samples are more representative, which is untrue, and Option E implies that nonprobability sampling has no problems, which is also untrue.
