I have collected data from two groups (age 25-30, age 30+). In each group I have 10 patients. I performed several medical tests (i.e., R.B.C, Liver test, etc.) on the patients, before and after treatment.
The data look like this:
Group 1 Test1 ... Test 10 Before After Before After patient 1 10 16 13 patient 2 12 11 19
It's the same for Group 2.
How can I test the effect of the treatment in both groups?
