Question

Quizplus · Accepted Answer

The primary characteristic of a probability sample is the random selection of the sample. This means that every member of the population has an equal chance of being selected for the sample, which helps to ensure that the sample is representative of the population as a whole. Self-selection, hand picking, or other non-random methods of selecting participants can introduce bias and make it difficult to generalize the results to the larger population. Therefore, B is the correct answer.
