"n wine judges rate k different wines. Are the ratings consistent?" doesn't seem like an application of the Friedman test ... the test compares the mean rank between wines but these could be identical even though the ratings between judges are highly inconsistent.

This Version of the Friedman test is no longer used. The version currently used recommended by conover is explained quite nicley here: http://www.itl.nist.gov/div898/software/dataplot/refman1/auxillar/friedman.htm
It is also fully explained with full Citations in David Hull's paper "Using Statistical Testing in the Evaluation of Retrieval Experiments" The key difference is the t-distribtution is now used rather than Chi-Squared
Why is the Friedman test referred to as equivalent to a 2-way ANOVA? It is only a one-way repeated ANOVA, or am I missing something? Rickogorman 18:26, 8 March 2007 (UTC)
- Rickogorman - to the best of my knowledge - You are correct. Talgalili (talk) 17:22, 22 February 2010 (UTC)
I think it has nothing to do with repeated ANOVA. It is a non parametric test based on data ranked. Not sure it this is the question, neither if this motivates some changes on text article.83.43.175.218 (talk)
- User - it is a non parametric one way repeated measures ANOVA... Talgalili (talk) 17:22, 22 February 2010 (UTC)

Could someone give a brief idea of what the null hypothesis and the alternative hypothesis are?
editI have been reading some articles about other statistical tests on Wikipedia and most of them have an explanation on what the null hypothesis and the alternative hypothesis are. I think it would be convenient to have these notions in this article as well. — Preceding unsigned comment added by Guyik (talk • contribs) 18:16, 23 August 2017 (UTC)
