The standard deviation is usually calculated automatically by whichever software you use for your statistical analysis. But you can also calculate it by hand to better understand how the formula works. There are six main steps for finding the standard deviation by hand. We’ll use a small data set of 6 scores to walk … See more Standard deviation is a useful measure of spread fornormal distributions. In normal distributions, data is symmetrically distributed with no … 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 Although there are simpler ways to calculate variability, the standard deviation formula weighs unevenly spread out samples more than evenly spread samples. A higher standard deviation tells you that the … See more You can calculate the standard deviation by hand or with the help of our standard deviation calculator below. See more

WebFor a skewed distribution, both the mean and the standard deviation are affected by the skew in a way that make the z -score results less representative of what you're trying to convey. I think a more direct way of indicating what you want is to use percentiles. Percentiles are in a sense robust against the skew in the distribution.
