Standard deviation is the average or mean of all the averages for multiple sets of data. Scientists and statisticians use the standard deviation to determine how closely sets of data are to the mean of all the sets.
The standard deviation calculation tells you how spread out the numbers are in your sample. To figure this out for your sample or data set, you will need to perform a few calculations first. You will need to find the mean and variance of your data before you can find the standard deviation.
