Currently looking at data in which each participant recorded their level of pain from 1-10 in terms of severity for both pre and post operation, for 3 different treatments. Such as the table below, except i have 100 participants. What kind of test(s) should i use here to see if there are differences between the effectiveness of treatments?
I thought about doing the following: Independent t tests to see if there are any differences between the treatments in post pain rating. And then paired sample t tests within each treatment condition to see if those had an effect on pain. Or possibly some type of repeated measures anova?
