It is used to compare the statistical models as per the data set available. George W. Snedecor, in honor of Sir Ronald A. Fisher, has given name to this formula as F Test Formula. WebThe F-critical value is a specific value to which your F-value is compared. You can reject the null hypothesis if your calculated F-value in a test is greater than your F-critical value. In an F-Test, however, the statistic is only one measure of significance. You should also think about the p-value.
