We want to compare t treatments group the n = bt experimental units. • a design that satisfies these conditions is called balanced incomplete block design. The incomplete block designs can use a lesser number of television sets or lcd panels to conduct the test of the significance of treatment effects without losing, in general, the efficiency of the design of the experiment.
