Description: WebSep 11, 2023 · 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. Views: 2.7M
