In thestatistical theory of the design of experiments, blocking is thearranging of experimental units in groups (blocks) that are similar toone another. For example, an experiment is designed to test a new drugon patients. There are two levels of the treatment, drug, and placeboadministered to male and female patients in a double blind trial. Thesex of the patient is a blocking factor accounting for treatmentvariability between males and females. This reduces sources ofvariability and thus leads to greater precision.…

In the design ofexperiments, completely randomized designs are for studying the effectsof one primary factor without the need to take other nuisance variablesinto account. This article describes completely randomized designs thathave one primary factor. The experiment compares the values of aresponse variable based on the different levels of that primary factor.For completely randomized designs, the levels of the primary factor arerandomly assigned to the experimental units.…
