Terms to Know
Mean of a Distribution of sample means

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.

Standard Deviation of a Distribution of sample means

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.
