WebStandard deviation measures the spread of a data distribution. The more spread out a data distribution is, the greater its standard deviation. For example, the blue distribution on … Web7 de set. de 2024 · The larger the standard deviation, the more variable the data set is. There are six steps for finding the standard deviation by hand: List each score and find their mean. Subtract the mean from each score to get the deviation from the mean. Square each of these deviations. Add up all of the squared deviations.
