Write out the ANOVA shell (sources of variability & degrees of freedom) for each experiment described below. If there are any error terms other than residual error, be sure to explicitly label them-you may need to define additional factors in order to do so. Using our rule-of-thumb for treatment & design factors, identify each factor (other than Total) in the ANOVA shell as fixed or random. a. (8 pts.) A 3-way factorial treatment structure with factors A, B and C was run in a balanced CRD. A has 2 levels, B has 4 levels and C has 3 levels. Each treatment (i.e. a combination of levels of A, B and C) has 3 replicates. B ) An RCBD with 6 blocks has a 2-way factorial treatment structure consisting of treatment factor A with 2 levels and treatment factor B with 3 levels. C) A 44 Latin square was replicated 5 times (5 squares in total) where different row blocks & different column blocks appeared in each square. The treatment structure is a 22 factorial with treatment factors A & B each having two D) A split-plot experiment was performed where the 3 levels of treatment factor A were assigned to the whole plots in a CRD with 5 replicates of each level. Each wholeplot unit was then divided into 4 subplots and the 4 combinations of factors B & C (each with 2 levels) were each randomly assigned to one subplot within each whole plot
