Best practice when analysing pre-post treatment-control designs
I'm doing an action research study with 2 of my classes: 1 is the 'treatment' class and the other is the 'control'.
Both classes undertook a pre-test prior to the 'treatment'.
Then, after the 'treatment' stage (the control class didn't receive any 'treatment'), both classes did a post-test.
What statistics should I use? Paired t-tests? ANOVA with repeated measure? Help!
