A statistic used as a measure of the dispersion or variation in a distribution, equal to the square root of the arithmetic mean of the squares of the deviations from the arithmetic mean.

The standard deviation of a sample is known as S and is calculated using:

s   =  53.3788

Variance = (53.3788)2

= 2849.2962
