Get PriceGenerating relation and diagram for the 2 8 3 fractional factorial design We considered the 2 3 1 design in the previous section and saw that its generator written in I = form is {I = 123} Next we look at a one eighth fraction of a 2 8 design namely the 2 8 3 fractional factorial design Using a diagram similar to Figure we have the following
Get PriceWelcome back to our experimental design class This is the start of module 6 This is based on chapter 6 in the textbook and it s all about the 2 to the K factorial design Now these designs are special cases of the general factorial which we talked about in module 5 chapter 5 of the book There we focused mainly on the on the two factor case
