Calculate the standard deviation of the mean
Standard deviation is a useful measure of spread fornormal distributions. In normal distributions, data is symmetrically distributed with no skew. Most values cluster around a central region, with values tapering off as they go further away from the center. The standard deviation tells you how spread out from … See more Different formulas are used for calculating standard deviations depending on whether you have collected datafrom a whole population or a sample. See more You can calculate the standard deviation by hand or with the help of our standard deviation calculator below.
