TABLE 12-2
An agronomist wants to compare the crop yield of 3 varieties of chickpea seeds. She plants all 3 varieties of the seeds on each of 5 different patches of fields. She then measures the crop yield in bushels per acre. Treating this as a randomized block design, the results are presented in the table that follows.
-Referring to Table 12-2, what are the degrees of freedom of the Friedman rank test for the difference in the medians at a level of significance of 0.01?
