An Agronomist Wants to Compare the Crop Yield of 3

Multiple Choice

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 crop yield from the 3 varieties of seeds has very skewed distribution. Which of the following tests will be the most appropriate to find out if the different patches are advantageous in reducing the random error?

A) One-way ANOVA F test for differences among more than two means
B) Randomized block F test for differences among more than two means
