Question

Quizplus · Accepted Answer

Probability samples are selected using a random process that reduces the chance of conscious or unconscious sampling bias. The ability to estimate the accuracy or representativeness of the sample is a key advantage of probability sampling. While probability samples are not necessarily perfectly representative of the population, they are more likely to be representative than non-probability samples. Option D combines these two advantages, making it the best choice. Option E is incorrect because probability samples are not always perfectly representative of the population.
