However, a terminological difference arises in the expression mean squared error (MSE). The mean squared error of a regression is a number computed from the sum of squares of the computed residuals, and not of the unobservable errors. If that sum of squares is divided by n, the number of observations, the result is the mean of the squared residuals.
The first two metrics - the standard deviation and the variance - are closely related. In fact, calculating the variance is an intermediate step in calculating the standard deviation. Both of these measures are calculations that show how far the values in a dataset differ from the arithmetic mean.
