WEBThe formula for standard deviation (SD) is. SD = ∑ | x − μ | 2 N. where ∑ means "sum of", x is a value in the data set, μ is the mean of the data set, and N is the number of data points in the population. The standard deviation formula may look confusing, but it will make sense after we break it down.

WEBSep 17, 2020 · The standard deviation is the average amount of variability in your dataset. It tells you, on average, how far each value lies from the mean. A high standard deviation means that values are generally far from the mean, while a low standard deviation indicates that values are clustered close to the mean.

WEBThe formula for standard deviation makes use of three variables. The first variable is the value of each point within a data set, with a sum-number indicating each additional variable (x, x 1, x 2, x 3, etc). The mean is applied to the values of the variable M and the number of data that is assigned to the variable n.
