Suppose you are planning to study five different hardwood concentrations to determine their effect on the strength of the paper produced at a pilot plant. The experiment is to be carried out over five days. Uncontrollable factors affecting paper quality can vary from day to day, and the plant is limited to four production runs on each day. What experimental design would you recommend in this situation? Be specific: show how concentration might be assigned to the 20 possible production runs over the five-day period and describe how the assignment would be randomized. Describe a desirable feature of your design.
