SCENARIO 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 Scenario 11-6,the decision made at a 0.01 level of significance on the randomized block F test for the difference in means implies that all 3 means are significantly different.

Quizplus · Accepted Answer

The decision made at a 0.01 level of significance on the randomized block F test for the difference in means only indicates that there is at least one significant difference among the means, not that all pairwise comparisons are significantly different.
