F Test Statistic. Test statistics are vital to determining if a model is good at explaining patterns in data. For more complex models the f statistic determines if a whole model is statistically different from the mean.
The f test of overall significance has the following two hypotheses. An f statistic is a value you get when you run an anova test or a regression analysis to find out if the means between two populations are significantly different. It s similar to a t statistic from a t test.

The f statistic incorporates both measures of variability discussed above. The f test of overall significance has the following two hypotheses. It s similar to a t statistic from a t test. While anova uses to test the equality of means.
