16. Suppose that we are designing a completely randomized block design with 120 subjects, where the subjects are divided into two blocks of equal size. In this experiment, we study the effects of two factors: Factor 1 (which has two levels) and Factor 2 (which has three treatments). In order to maximize replication in each treatment group, the number of subjects to receive each treatment will be 12.

1 The primary reason for using randomization in experimental design is to reduce bias 2 The purpose of replication in experimental design is to provide a more precise estimate of the treatment effect ... View the full answer
