Several Desired and Undesired Variations
As mentioned in Chapter 5, it may not be possible to experiment with all the combinations of alternatives required by a factorial design under homogeneous conditions. This situation is managed using blocks. As discussed in preceding chapters, blocks can refer to the subjects running the experiment, the times at which they are run, variations in the projects used as experimental units or any other undesired variation that occurs from one unitary experiment to another.
