Overview

(0:00-0:39) Definition of the Mean of Distribution of Sample Means

(0:40-1:12) Definition of the Standard Deviation of Distribution of Sample Means

(1:13-2:33) Example of Finding the Mean and Standard Deviation of the Distribution of Sample Means

TERMS TO KNOW
  • 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.

  • 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.
