A randomized block design should NOT be used when treatments and blocks both correspond to experimental factors of interest to the researcher.

Question

Quizplus · Accepted Answer

A randomized block design is used when the experimental units are naturally grouped into blocks, and the treatments are applied randomly within each block. This design is used to control for the effects of the blocks, which can be due to factors such as soil type, temperature, or altitude. If the treatments and blocks both correspond to experimental factors of interest to the researcher, then a randomized block design should not be used, because the effects of the treatments and blocks cannot be separated.
