Standard deviation and variance - Free Math Worksheets The standard deviation is useful because it gives information about how far away the data is from the arithmetic mean. Definition: Standard deviation is equal to the square root of the variance, i.e. σ = ∑ i = 1 k f i ( x i - μ) 2 ∑ i = 1 k f i. Therefore, $\sigma$ is the average deviation of values of numeric variable from its arithmetic mean. StatProb_Q3_Worksheet-No.-2_Mean-Variance-and-Standard-Deviation-of-a ...
