Dear Eric and David,
I tend to do 'simple effect test' using t-test without ANOVA (in this case
you want to use paird t-test). If your mentor/reviewer complaint about your
not performing ANOVA, use this reference
Ruxton GD, Beauchamp G. 2008. Time for some a priori thinking about post
hoc testing. Behav Ecol 19:690-693.
Let's make the life simpler!
