5.1 Split-plot design 67consider the random variability of the whole-plots as well as the variability of thesubplots. The sum of squares for Variety (which was applied to complete whole-plots)can correctly be compared with a residual which represents the random variability of thewhole-plots. Conversely, Nitrogen (which was applied to subplots) and theVariety.Nitrogen interaction are compared with the residual for subplots withinwhole-plots.Analysis of varianceVariate: yieldSource of variation d.f. s.s. m.s. v.r.
