Explanation:
Detailed explanation-1: -Analysis of variance (ANOVA) is an inferential method used to test the equality of three or more population means.
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.
