Research statistics question

Question

I’m a research student and I have to do a statistical test for this project in SPSS. Basically I had people take three surveys that were scored, and I’m trying to see if there is a difference between the scores for each survey. I need to know what statistical test to use.

Answer 1

You can do a straight hypothesis test of the mean average scores...

Let M1, M2, M3 be the mean average scores for quiz1, quiz2, and quiz3...

Then the THREE (3) hypothesis tests to do shall have NULL hypotheses:

M1 = M2, M2=M3, M1=M3
