I'm on holliday and suddenly I don't know what test to use..
I have 4 scores for each case. Each case represents a school and the scores are evaluations of different people about the school (teachers, school leader, board and inspector).
Scores range from 1 to 4. I want to test the mean differences between the groupes that evaluated the school.
What test should I use to test significant differences between the groups (p<.05)?
Thank you for your help!
