The F-test of the randomized block design of the analysis of variance requires that the random variable of interest must be normally distributed and the population variances must be equal. When the random variable is NOT normally distributed, which of the following tests may we use?
A) one-way ANOVA
B) two-way ANOVA
C) chi-square test
D) Friedman test
