The standard error of the mean is always smaller than the standard deviation of the population from which the random sampling distribution was constructed. Explain why this is so.
What will be an ideal response?

The standard deviation of the distributions of means must be less variable than the standard deviation of the population because each mean is the average of the raw scores and so the extreme score values are lost.
