standard error of the mean

Definition

The standard error of the mean (SEM) is data item denoting the standard deviation of the sample-mean's estimate of a population mean. It is calculated by dividing the sample standard deviation (i.e., the sample-based estimate of the standard deviation of the population) by the square root of n , the size (number of observations) of the sample. A measure of dispersion applied to means across hypothetical repeated random samples.
