In this example, you construct a full factorial design to study the effects of five two-level factors (Feed Rate, Catalyst, Stir Rate, Temperature, and Concentration) on the yield of a reactor. Because there are five factors, each at two levels, the full factorial design includes at least 25 = 32 runs. For smaller screening designs involving this experimental situation, see Additional Examples of Screening Designs in Screening Designs.
