I have to make a research
I have to check 7 results before surgery and after surgery
And I don’t know if it’s enough to check only 7 people in paired t-test
Thank’s

You will have to use a non parametric test. The equivalent to t-test in your case would be wilcoxon signed rank test.

You can use a paired t-test for n=7 if you are willing to assume that the errror terms are normally distributed.

I have a paper on the paired t-test at http://www.minitab.com/company/virtualpressroom/Articles/index.htm if that may be of use to you.
