Std Deviation And Variance. The calculation of variance uses squares because it weighs. Standard deviation is a statistic that looks at how far from the mean a group of numbers is by using the square root of the variance.

So now you ask what is the variance variance.
So now you ask what is the variance variance. The standard deviation is a measure of how spread out numbers are. Deviation just means how far from the normal. To calculate standard deviation add up all the data points and divide by the number of data points calculate the variance for each data point and then find the square root of the variance.
