The mean squares between groups describes differences between the means as an estimate of the differences between means found in the population. This is calculated by dividing the sum of squares between groups by the degrees of freedom between groups. It is a measure of the amount of variance in the data that can be explained by the differences between the groups, and is used to test the statistical significance of these differences.
