If the variability is not known to be uniform, then we may use blocking to attain homogeneity within the blocks


In Design of Experiments it is assumed that the population variance is fixed at say,#sigma# , throughout the field of experimentation. It also lead to randomised Block designs from Simple random designs, this increases efficiency of the test procedure.
