Explanation:
Detailed explanation-1: -An F-value is the ratio of two variances, or technically, two mean squares.
Detailed explanation-2: -Because we want to compare the “average” variability between the groups to the “average” variability within the groups, we take the ratio of the Between Mean Sum of Squares to the Error Mean Sum of Squares. That is, the F-statistic is calculated as F = MSB/MSE.
