489: A six sigma green belt has run a 25-2 fractional factorial design. Only 2 of the 5 factors remained important after the factorial analysis. Escalation of this DOE to an optimization model will be best accomplished by: A. Performing a new full factorial of the 2 factors B. Performing a response surface experiment C. Decreasing the degrees of freedom of the original DOE D. Adding an additional factor level

Design a full-factorial experiment.* Use one response and at least 2 factors, each factor with at least 2 levels. Describe the response and factor variables (e.g., what type of data are they, what are their levels or value ranges). What is the unit of observation? Describe the population, the sampling technique (how will you ensure random selection of units), and the sample and cell (treatment combinations) sizes. Will you have replications or repetitions? Are there any blocking factors? Graphically show...
