F Distribution

Select Analysis, Probability Distributions, F Distribution
Enter a positive integer (such as 10) for the numerator degrees of freedom,
and enter a positive integer (such as 12) for the denominator degrees of freedom.
Enter either the value of the F test statistic or enter the area to its right (such as 0.025).
Click on Evaluate.
Results include the value of F, the area to its left, and the area to its right. 
(The value given for “Prob Dens” (probability density) is the height of the graph of F distribution at the given value of F. This value is typically not used in the introductory statistics course.)
