Explanation:
Detailed explanation-1: -An F-value is the ratio of two variances, or technically, two mean squares.
Detailed explanation-2: -The F ratio is the ratio of two mean square values. If the null hypothesis is true, you expect F to have a value close to 1.0 most of the time. A large F ratio means that the variation among group means is more than you’d expect to see by chance.
Detailed explanation-3: -F ratio. Each F ratio is computed by dividing the MS value by another MS value. The MS value for the denominator depends on the experimental design. For two-way ANOVA with no repeated measures: The denominator MS value is always the MSresidual.
