Question

Describe Randomized Block Design (RBD)

Answer 1

$<u><b><i>Randomized Block Design. With a randomized block design, the experimenter divides subjects into subgroups called blocks, such that the variability within blocks is less than the variability between blocks. Then, subjects within each block are randomly assigned to treatment conditions.$

Answer 2

Have you ever looked at a brick building and thought there is a perfect pattern to those bricks? Did you ever think of randomized block design? Of course you didn't because that term has nothing to do with architecture, but rather a way to statistically analyze a study and the data that comes out of it! Specifically, a randomized block design, or RBD, splits up experimental units into groups or blocks of equal size, and then assigns a treatment to each group randomly. This makes sure that the data is not affected by outside situations.
