Standard Deviation is the most commonly used measure of variation. It is defined as the square root of variance. Standard Deviation is very significant in statistical data analysis. Unlike other measures of variation except variance, Standard Deviation evaluates how all the values in the data set are distributed. This unique characteristic of Standard Deviation and variance makes it very useful in statistical data analysis. Standard Deviation can never take negative values.
