Analysis of Variance

ANOVA & MANOVA

Compare groups, model factorial and blocked designs, assess assumptions, explore post-hoc differences, and extend the analysis to multiple responses using pasted raw data or mathematically sufficient summary statistics.

Friedman Test

Compare repeated or blocked treatments using ranks, with Kendall's W and Nemenyi follow-up comparisons.
