The standard deviation of the sampling distribution of the sample means, known as the standard error, is equal to the population standard deviation divided by the square root of the sample size. This makes it smaller than the population standard deviation when the sample size is greater than 1.

When the Sample Size Is Greater Than 1,the Standard Deviation
