The randomized block design is a type of experimental design that involves dividing subjects into blocks based on some characteristic, and then randomly assigning treatments within each block. This design is often used when there is a potential confounding variable that may affect the response variable, and the goal is to control for this variable. The analysis of this design involves using a two-way ANOVA with one factor being the treatment and the other factor being the blocking variable. Therefore, the randomized block design is also referred to as the two-way ANOVA.
