LEARNING OBJECTIVES

After careful study of this chapter you should be able to do the following:
1. Identify the role that statistics can play in the engineering problem-solving process
2. Discuss how variability affects the data collected and used for making engineering decisions
3. Explain the difference between enumerative and analytical studies
4. Discuss the different methods that engineers use to collect data
5. Identify the advantages that designed experiments have in comparison to other methods of col-
lecting engineering data
6. Explain the differences between mechanistic models and empirical models
7. Discuss how probability and probability models are used in engineering and science
CD MATERIAL
8. Explain the factorial experimental design.
9. Explain how factors can Interact.
