How To Calculate The Standard Deviation

How To Calculate A Sample Standard Deviation To calculate standard deviation, start by calculating the mean, or average, of your data set. then, subtract the mean from all of the numbers in your data set, and square each of the differences. next, add all the squared numbers together, and divide the sum by n minus 1, where n equals how many numbers are in your data set. Learn the definition, formulas and steps for calculating standard deviation for populations and samples. see how to use the standard deviation to measure variability and compare distributions.
