Here's my problem.
--ONLY One group--
All fill-out pre-test. All participants given intervention. Complete a post-test. Return in 2-weeks to complete another post-test to determine if intervention effects sustained.
My question is whether intervention has an effect (which in comparing pre- and post-test, leads me to believe I can use paired sample t-test) But having the 2-week post-test, does this mean that I will be using repeated measures ANOVA? I haven't had research in a while, and was looking around online and getting frustrated.
Any help would be appreciated.
