The nonparametric counterpart of the randomized block model of the analysis of variance is the Friedman test. This test is used when there are repeated measures on the same subjects, and it ranks the data within each block (subject) rather than assuming a normal distribution like the parametric ANOVA. The other options (Kruskal-Wallis test, Wilcoxon rank sum test, and Wilcoxon signed rank sum test) are all nonparametric tests as well, but they are not appropriate for analyzing data in a randomized block design.
