F Value
The F-distribution with d 1 and d 2 degrees of freedom is the distribution of where and are independent random variables with chi-square distributions with respective degrees of freedom and. F α at a given level of significance α is the critical value on the F distribution such that the area on its right is equal to α.

If this p-value is less than α 05 we reject the null hypothesis of the ANOVA and conclude that there is a statistically significant difference between the means of the three groups. 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.
Computes p-values and F values for the Fisher-Snedecor distribution. Identify the effect on the graph of replacing fx by fxk kfx fkx and fxk for specific values of k both positive and negative. A T-test will tell you if a single variable is statistically significant and an F test will tell you if a group of variables are jointly significant.
