2 Way ANOVA or lots of T-tests!!! Just cant get my head round it!!!!

#1
Hi everyone,
I really cant get my head round which test i am supposed to use and every time i think i have it sorted in my head, i change my mind, please help!!!

I have two groups of drug treated and control and i want to assess the effect this drug has on cell number in 10 different areas in the brain.

So am i right in thinking that as i have 2 different independent variables (drug treated and brain area) and one dependent variable, i need to use 2 way ANOVA ?

But now im thinking that maybe the 2 independent variables may not interact per se and so just need to do 10 t-tests (one for each area of the brain comparing control and treated)....ahhhhhhh!!!

Think im going crazy!!!!!please put me out of my misery!!!

Also always better to do one test than 10 - decreases the chance of erronously finding significant results. The ANOVA can get you the main effects and check for interaction. Good luck
