Question
Use SPSS for this Application Exercise:
How does gender and occupational prestige affect credibility? Graduate students in a public health program are asked to rate the strength of a paper about the health risks of childhood obesity. In reality, all student raters are given the same paper, but the name and degree associated with the author are changed. The student raters are randomly assigned to one group from the following name ("John Lake", "Joan Lake") and degree (M.D., R.N., Ph.D.) combination. The raters score the paper from 1 to 5 on clarity, strength of argument, and thoroughness. The total scores (the sum of the three scores) are given in the table below. What can be concluded with ? = 0.01?
a) What is the appropriate test statistic?
---Select--- na one-way ANOVA within-subjects ANOVA two-way ANOVA
b) Compute the appropriate test statistic(s) to make a decision about H0.
Name: p-value = ; Decision: ---Select--- Reject H0 Fail to reject H0
Degree: p-value = ; Decision: ---Select--- Reject H0 Fail to reject H0
Interaction: p-value = ; Decision: ---Select--- Reject H0 Fail to reject H0
c) Compute the corresponding effect size(s) and indicate magnitude(s).
Name: ?2 = ; ---Select--- na trivial effect small effect medium effect large effect
Degree: ?2 = ; ---Select--- na trivial effect small effect medium effect large effect
Interaction: ?2 = ; ---Select--- na trivial effect small effect medium effect large effect
d) Make an interpretation based on the results.
-There is a name difference in the total scores OR There is no name difference in the total scores.
-There is a degree difference in the total scores OR There is no degree difference in the total scores.
-There is a name by degree interaction in the total scores OR There is no name by degree interaction in the total scores.

Explanation / Answer
a) The appropriate test statistic in this case is the two-way ANOVA.
b) Name: p-value = 0.0008; Decision: Reject H0.
Degree: p-value = 0.0794; Decision: Fail to reject H0.
Interaction: p-value = 0.0355; Decision: Fail to reject H0.
