This program asks the user to input the alpha level and the degrees of freedom for the F distribution of interest.  After pressing calculate, ZumaStat shows the critical value of F that would be used to reject the null hypothesis for a significance test at the entered alpha value. The example below shows how the dialog box looks after the data have been entered and the Calculate button is pressed.

ZumaStat offers similar programs for the t distribution, the normal distribution and a chi square distribution.
