To replicate the design, simply copy and paste the design in Table 4 as many times as necessary. Randomization is only required for the runs within a block. The experiment should be run in random order rather than the standard order. Simply, the random number generator function RAND() in MS Excel can be used to develop the run order for the experiment. Table 5 shows three replications of the 2³ design with two blocks for each full replication.
