CHAPTER 11
Analysis of Variance and Design of Experiments
LEARNING OBJECTIVES
The focus of this chapter is the design of experiments and the analysis of variance, thereby enabling you to:
- Describe an experimental design and its elements, including independent variables—both treatment and classification—and dependent variables.
- Test a completely randomized design using a one-way analysis of variance.
- Use multiple comparison techniques, including Tukey's honestly significant difference test and the Tukey-Kramer procedure, to test the difference in two treatment means when there is overall significant difference between treatments.
- Test a randomized block design which includes a blocking variable to control for confounding variables.
- Test a factorial design using a two-way analysis of variance, noting the advantages and applications of such a design and accounting for possible interaction between two treatment variables.
