Hi,
I understand how to determine the sample size if you are doing a
simple hypothesis test (like equality of means) with 2 populations.
Recently, however, I had to undertake a one-way ANOVA test where I am
using more than one population. Nothing fancy, no complex design
issues, just good old straightforward ANOVA. I have been able to find
very little in the way of how sample size is determined, and I am
wondering if anyone can either explain the basic concept involved or
point me in the direction of a good text that is not too advanced
(maybe 1st yr grad level) yet explains this problem well.
TIA,
Matt B
Do you want software to do the calculation? Or are you looking for
notes/books that explain how it works? For software, Google for
Russell Lenth's power page. You might find his "Two Bad Habits" paper
there too.
