Hello. I am an educator that is working on my dissertation. I am looking to measure three years of student test scores before a particular treatment and compare them to three years of test scores post treatment. What test(s) would you recommend?
Posting twice is a faux pas and that it can results in multiple people working on the same thing independently and you may provide extra content in one thread but not the other. In order to be respectful of people's time please do not do this again in the future.
