Question

Quizplus · Accepted Answer

A weighted sample is different from a random one because it has been adjusted to more closely represent the larger population by giving more or less weight to certain subgroups based on their proportion in the population. This allows for more accurate conclusions to be drawn about the entire population based on the sample.
