Standard error - Wikipedia
https://en.wikipedia.org/wiki/Standard_error
WebThe standard error (SE) of a statistic (usually an estimate of a parameter) is the standard deviation of its sampling distribution or an estimate of that standard deviation. If the statistic is the sample mean, it is called the standard error of the mean (SEM). The standard error is a key ingredient in producing confidence intervals.

WebTo calculate the standard error of the mean for a finite population, you multiply the regular standard error of mean by the square root of " (N-n)/ (N-1)", where "N" is the size of the population and "n" is the sample size. Then, you just proceed at you would normally when calculating the Z-score.
