Objective: The objective of this activity is to examine differences among several experimental designs, particularly, single factor, multi-factor, and block designs. Topics covered: 1. Single factor designs 2. Multi-factor designs 3. Block designs Consider the following motivating example. 1. An agronomist wanted to compare the yield of three different varieties of rice (A, B, C). So, within a field, he randomly assigned each variety to five plots. The yield[s] in pounds per acre were recorded for each plot. (a)What is the response in the study? (b) What is the factor in the study? What are the factor levels? (c) What are the treatments? What are the blocks, if any? (d) What are the experimental units in the study? How many are there in total? (e) What is the name of the design of this experiment? (Single factor, two-factor, block) (f) Outline the design of the experiment
