WebbThe standard deviation of a set of numbers is a measure of dispersion of those numbers. In essence, it's a number which (with the average) describes or summarizes the range and shape of a set. A higher standard deviation means that samples are more varied, or "further apart". Smaller standard deviations mean that a measure has a tighter cluster. WebbSTDEV.S uses the following formula: where x is the sample mean AVERAGE (number1,number2,…) and n is the sample size.
