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 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.
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.
