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.…

A unit in a statistical analysis refers to one member of a set of entities being studied. It is the material source for the mathematical abstraction of a 'random variable'.
