Quizplus · Accepted Answer

A sampling distribution of the mean is created by taking the means of all possible samples of a fixed size (n) from a population. This distribution represents the distribution of means that would be obtained if an infinite number of samples of that size were taken from the population, and it is used to make inferences about the population mean.
