TABLE 12-2 An Agronomist Wants to Compare the Crop Yield of 3

True/False

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, the Friedman rank test is valid only if there is no interaction between the 5 blocks and the 3 treatment levels.
