Re: Reading from the F-Distribution Table for a missing v2 d.f value.

Hi all,

I am trying to read the F value for 2 (v1) and 33 (v2) degrees of
freedom for a 5% significance level but my problem is that I cannot
locate the v2 d.f (ie: 33) in the Table.

The Table has v2 values up to 20 and then skips to 40. How do I
calculate the value for 33?

Thanks for your help!

The upper-tail probability of F(2,n) is p = (2F/n + 1)^(-n/2),
so F = (n/2)(p^(-2/n) - 1).
