WebbAfter using a randomized block design, it is not unusual to find that the block effect is not only not significant, but so small that it would have been better to have not blocked in the first place. It might then be tempting to reanalyze the data using a completely randomized design in order to gain degrees of freedom.

We ignore numbers above 6 so we select blocks 2, 5 & 6. Hence we allocate the first 12 individuals to A 1 A 2 A 1 A 2 , A 2 A 1 A 2 A 1 , & A 2 A 2 A 1 A 1. This randomization list would give us 6 individuals in each group.
