What is a sample distribution vs sampling distribution?

WebThe central limit theorem (CLT) shows that the mean of a variable has an approximately normal distribution if the sample size is large enough. We apply the rule of thumb that the minimum number of independent and identically distributed observations needed to safely assume that the means have a normal distribution is 355 for each treatment.
