Example 2:- In a small experiment, at Uzo-Uwani Farm, to test the performances of four different fertilizers on yields of cassava, the plot to be used was divided into eight subplots and treated as blocks. Treatments were applied at random in each block, with each treatment appearing once in each block. The yield of cassava (in kilograms) harvested at the end of 6 months and the random assignments in each block used in the actual experiments are presented in the following Table . Cassava Plots (Blocks) I II III IV V VI VII VIII 8 A 2 C 10 D 7 A 5 D 3 D 2 A 8 C 10 C 3 B 9 C 6 D 2 C 10 B 8 D 3 B 8 B 6 A 13 B 10 C 3 D 13 A 10 C 9 A 8 D 3 D 13 A 8 B 4 A 3 C 7 B 6 D Is there an effect of the treatments on the data ? Note that, we can rearrange the table as follows Blocks Treatment I II III IV V VI VII VIII 8 8 3 10 10 y.j
