The randomized block design is used when comparing more than two populations and involves dividing the subjects into blocks based on a certain characteristic and then randomly assigning each subject within the block to a treatment group. This helps to control for the variability associated with the characteristic used to form the blocks and increases the accuracy of the experiment. The completely randomized design and one-way ANOVA design are used to compare only two or a few populations, not more than two.
