WebLet's use the concept of the generator and construct a design for the 2 4 − 1 fractional factorial. This gives us a one half fraction of the 2 4 design. Again, we want to pick a high order interaction. Let's select ABCD as the generator (I = ABCD) and by hand we can construct the design. I = ABCD implies that D = ABC.
