Hi all, this is probably a very basic question but im struggeling with some basic statistical analysis.
When examining non-parametic data in a nominal format and in terms of (T1 and T2) pre and post assessments what statistical test should one use?
I would go for a Friedman test which is the non parametric equal of the repeated measures ANOVA. Another solution may be creating dummy variables from your dependent variable for each group and use Wilcoxon . If i were in your shoes i would try both..
