The randomized block design is a type of experimental design that controls for extraneous factors by dividing participants into blocks based on a characteristic that is expected to affect the outcome variable. This characteristic could be gender, age, or some other relevant factor. Within each block, participants are then randomly assigned to different treatments or conditions. A two-way ANOVA would be appropriate for analyzing data from a randomized block design as it allows for the examination of the effects of two different factors (e.g., treatment and block) on the outcome variable.
