Re: Statistical help? 1 vs 3 sets

I would recommend that you account for multiple comparisons and differences

in pre-testing values. I would run a 2 x 2 ANOVA with repeated measures, or

a MANOVA if you wanted to be very conservative. Pay particular attention to

your interactions - that's where the story is.

Hope this helps.

Hi ,

Don't you just love stats!

If I'm thinking correctly you can say a greater significance was

found (doesn't mean all that much to say it however). You may even

be able to try running a t-test between the improvements shown by

each group to see if one significantly improved more than the other.

As was spoken about in another reply ANOVA's are another option but

that's getting a little out of my depth without consulting stats

books. I stick to the smaller, more easily wielded tests.
