The Sampling Distribution of the Mean
... population, the mean of that sample will be different. Some means will be more likely than other means. So it makes sense to think about means has having their own distribution, which we call the sampling distribution of the mean. The Central Limit Theorem tells us how the shape of the sampling dist ...
