TABLE 11-6
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 11-6, the randomized block F test is valid only if there is no interaction between the variety of seeds and the patches of fields.

Quizplus · Accepted Answer

The randomized block F test assumes that there is no interaction between the treatments (i.e., varieties of seeds) and the blocks (i.e., patches of fields). Therefore, the test is only valid if this assumption holds true.
