Is the provided answer correct, and what improvements can be made to the provided detailed explanation / analysis for the answer?

Where is F-Statistic used?

ANSWER: F test is conducted for testing the equality of variance. Therefore we get F statistic while conducting the F-test or ANOVA and while conducting the regression analysis. In ANOVA though the basic aim is to check the equality of means of more than 2 samples/variables, the test considers equality of variance for better results and therefore the statistic used is F. In Regression analysis also as it also gives importance to variance For example, a large F Statistic value would indicate that most of the variation in Y is explained by the regression equation, which would support the validity of the model. Conversely, a small F Statistic value would indicate that most of the variation in Y is unexplained, which would support an invalidate model.
