This page is used to set up the parameters for a web page that will generate
the cumulative probability for the F distribution for a given
number of degrees of freedom for both the numerator and denominator.
Here we can determine the number of degrees of freedom. Recall that we
are looking at
v1/v2
so the degrees of freedom for the numerator will be one less than the size of the
numerator sample and the degrees of freedom for the denominator will be
one less than the size of the denominator sample.
