A randomized block design analysis of variance test corresponds to:
A) a Wilcoxon signed rank test for paired samples
B) a Wilcoxon rank sum test
C) a Wilcoxon signed rank test for one sample
D) a Friedman test for randomized block design
E) all of these

Question

Quizplus · Accepted Answer

A randomized block design analysis of variance test is best represented by a Friedman test for randomized block design. The Wilcoxon signed rank test for paired samples (A) and Wilcoxon rank sum test (B) are nonparametric tests for comparing two groups, while the Wilcoxon signed rank test for one sample (C) is used for a single group. The Friedman test is specifically designed for analyzing a randomized block design, which is what the question refers to.
