The steel bar datawas analyzed once in Example 9.6 as a three-way ANOVA, and revisited in Section 10.4 as a randomized block design with an embedded twoway factorial design. What consideration would determine which method is the correct analysis?

Each of the scenarios described in Questions 2 through 6 is taken from the recent behavioral sciences literature.

(a) Match each scenario to one of the following probable methods of analysis:

one-way ANOVA (Chapter 6) two-way ANOVA (Chapter 9)

randomized block repeatedmeasures with two within-subject factors repeated measures with one between and one within factor

(b) State the appropriate null hypothesis in words (e.g., there is no main effect for …).

(c) Give the numerator and denominator degrees of freedom for the corresponding F test.
