Hello, I am conducting a research study and am having a difficult time determining which statistical test is the best to use to analyze results. Participants will be as to complete a pre-test, the intervention will occur and post intervention they will complete the exact same test. Finally, a month after the intervention they will complete the exact same test again. I want to analyze how the results of these 3 tests change. I am thinking the Anova test is the best because it can compare more than 2 sets of data. Any insight will be appreciated.
