Analysis of Variance II

This second ANOVA chapter considers randomized block designs and two-way ANOVA models. Randomized block designs model the effects of a single group variable or factor while controlling for another source of variation using blocks. Two-way ANOVA models explain differences in the mean response corresponding to the levels of two group variables (factors) and their possible interaction. Tukey HSD confidence intervals and plots for main effects and interactions, residual plots, interaction plots and other relevant graphics are described.
