# Which non-parametric test should I run on ordinal data from a small sample?

I have one group of six raters who scored recordings of two separate six-person groups of participants, each group under separate conditions. While the participants were divided into two independent groups, the ordinal data came from the same group of raters. Due to the small sample size (i.e. 12 ordinal scores to compare both participants), which test could I run. I've read that I'd need at least 20 scores to run a Wilcoxon... Thank you for your time and consideration in answering this question!

Given x=1:6;y=2:7, wilcox.test(y,x,paired=T) results in V = 21, p = .02. Hence the test you have in mind may be suitable enough. You could also consider resampling methods like permutation or bootstrap tests, but there's not a lot of statistical power in a sample of 12 regardless of the test.
