I have a sensory evaluation data that has 2x3 factorial, therefore it has 6 data in total. I have performed normality test and it isn't normally distributed, thus I can't use parametric test (ANOVA 2 way, etc).
I decided to use non-parametric data Friedman because it is said to be equal with ANOVA 2 way.
The result is they are significantly different, then I have to continue using Post-Hoc (Wilcoxon test).
Question:
1. Is Friedman the correct method? Or Kruskal Wallis is more appropriate?
2. Is it okay to use Wilcoxon Test? If it is, do I have to use the Benferroni correction?
Or do I have to use another non-parametric post-hoc tests?
Thank you
