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. She has found out that the different varieties do have an impact on crop yield. Which of the following tests will be the most appropriate to find out which variety will produce the highest yield?
A) McNemar test
B) Tukey multiple comparisons procedure for randomized block designs
C) One-way ANOVA F test for differences among more than two means
D) Tukey-Kramer multiple comparisons procedure for one-way ANOVA
Question 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. Which of the following tests will be the most appropriate to find out whether using different patches is advantageous in reducing the random error?
A) Randomized block F test for differences among more than two means
B) One-way ANOVA F test for differences among more than two means
C) Randomized block F test for block effect
D) Two-way ANOVA F test for the variety effect
