I have been collecting data where participants have been allocated to one of three different conditions and had to answer some questions. The data looked like this:
Condition Response 1 a 5 2 b 2 3 a 7 4 c 6 5 b 3
I was planning to do an ANOVA but the assumptions of normality was broken so I did a Kruskal-Wallis test. For the post-hoc would I do Mann-Whitney or the Wilcoxon Sign-rank test? I am unsure of the difference between the two other than with r coding I believe one to use
wilcox.test and the other to use
wilcox_test (please correct me if I'm wrong).
If this is necessary to know, I hypothesised the results from the questions the participants answered should be affected by the condition they were allocated. Specifically, condition 'a' would be the most effective.
So I guess what I'm asking is: Should I use Mann-Whitney or Wilcoxon Signed Ranked or something else entirely as the post hoc?
