I'm really confused about which test to use to test the hyposthesis; "There is no difference in the preference of an exercise programme". Each participant (n=17) attends all three different exercise sessions (aqua aerobics, step aerobics, and circuit training). The 'enjoyment score' is given by each participant and is out of 100.
I know it's ordinal level data so need a non-parametric test. But I'm not sure if it's classed as independent samples, as comparing three different groups (Kruskal-Wallis test), or repeated measures (Friedman test) because the same person is involved in each exercise type?!
Please can someone clarify??
