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.

Randomized Block ANOVA

Compare treatments while accounting for a blocking variable with an additive treatment + block model.

Raw-data layout

Both layouts are designed for direct copy/paste from Excel or Google Sheets.

Treatment comparisons

Comparisons retain the block effect instead of treating the responses as an ordinary one-way design.
