Hello everyone. Quick question, if I may.
I am trying to calculate the statistics of the following situation. I have two groups of people :
1) group A (10 people) following one specific therapy. I will measure their pain level of a specific muscle at three different times : t1, t2 and t3
2) group B (10 different people) follows another therapy. I will also measure their pain level at three different times : t1,t2 and t3
My questiosn :
- Which test should I use to compare the evolution within each group ? I would like to perform a Friedman test, because the resultats are not normal. Is this correct ?
- Which test should I use to compare t1 of group A VS group B, t2 of group A VS group B and t3 of group A VS group B ? Can I make a "Mann-Whitney" test ?
Thank you in advance
