    Standard Deviation Vs Variance Whats The Differenc

    Standard deviation is simply the square root of the variance The calculation of variance uses squares because it weights outliers more heavily than data very near the mean This also prevents differences above the mean from canceling out those below which can sometimes result in a variance of zero
