numbers appeared . For our example , the 20 ranks are divided into four
groups consisting of five numbers as follows:

Group Ranks in the Group
Number
1 17 2 15 7 19
2 13 4 18 1 8
3 16 14 6 9 12
4 10 20 3 11 5

STEP A5. Assign the t treatments to the n experimental plots,
by using the number of STEP A4 as the treatment number and the
corresponding ranks in each group as the plot number in which the
corresponding treatments is to be assigned. For our example the

o first group is assigned to treatment A and plots numbered 17, 2,
15, 7, and 19 are assigned to receive this treatment:
o second group is assigned to treatment B with plots numbered
13, 4, 18, 1, and 8:
o third group is assigned to treatment C with plots numbered 16,
14, 6, 9, and 12: and the
o fourth group is assigned to treatment D with plots numbered 10,
20, 3, 11, and 5.: The final lay out of the experiment is shown in
