F statistic question

Tom Dunne

I'm looking at ANOVA for a paper I am reviewing. No issues with F(1,32)=1.78,p=0.092 - all that makes sense.

What I am having issues with is Fs(2,74) < 2.43, ps > 0.08. I can't seem to locate reliable information on what exactly this means. My statistics for psychology book doesn't go into it, the two other books I have on research methods barely mention ANOVA, so I am a little lost.

It's a social science paper, where the Fs appears is in the baseline comparison of three groups (intervention, placebo and control). The "regular" F statistic appears later in the paper, so I am getting myself bogged down on what Fs(X,Y) is actually telling me.

Any tips/pointers would be appreciated.

Ok, problem solved.

It's actually plural. As in, Fs means more than one F statistic, ps means more than one significance level.

No wonder I couldn't find it in any text book.
