T-test?

Can you perform the t-test on more than 2 sets of data?

If there's one "special" set, you can compare it in turn with each other set using a t-test. Have a look at what I did here:

There the "special" set is the "neutral pH" set.

ANOVA (Analysis of Variance) can compare all the sets at once, but that involves chi-squared tests rather than t-tests.

Thanks, so much!
I could kiss you, but since I can't I hope a rep will just do :smile:
