WebThe general ANOVA tables for the split-plot RCBD and the split-plot LS are similar to the CRD case and are given in Table 16.1 of ST&D (page 402). These different designs have no effect on the last four rows of the previous table. But the upper lines, corresponding to the main plot effects, do change: CRD RCBD Latin Square
