Problem: I am testing whether a psychological intervention or an augmented reality intervention is better at improving social skills. I am running an RCT where participants are placed randomly in either group. They then are given social skills measurements at baseline, post-int. at 4 months and then again at 8 months. To find out which intervention potentially resulted in better results, and which int. is better at improving social skills, what form of data analysis should be run, a repeated measure ANOVA or a mixed-design ANOVA? Why?
