A. Explain the characteristics of experimental design. If you were a Quality Manager, how would you use the concepts of vertical and horizontal balancing to ensure a sound experiment?

B. Explain the use of full and fractional factorial experimental designs. Provide a scenario of when it would be appropriate for each.

C. Describe the use of analysis of variance (ANOVA) in analyzing experimental results. Further, describe the use of a null hypothesis and why we use this concept to validate experiments.

D. Describe the Taguchi Methods for experimental design and how the concepts of robustness and design for quality are integrated into this method of experimental design.
