This lesson will explain how to find the mean and standard deviation of a sampling distribution of the sample means.

(5:18-6:10) Discussion of Population Distribution vs. Sampling Distribution
The average of all possible means from all possible samples of a given size. It will be equal to the mean of the original population.
The standard deviation of all possible means from all possible samples of a given size. It will be equal to the standard deviation of the original population, divided by the square root of the sample size.
