Fidalgo (2005) presented data on the relationship between bullying in the work force (Yes/

No) and gender (Male/Female) of the bully. He further broke the data down by job level.

The data are given below.

Bullying Gender Job Category No Yes Male Female Manual 148 98 28 22 Male Female Clerical 68 144 13 32 Male Female Technician 121 43 18 10 Male Female Middle Manager 95 38 7

a. Do we have evidence that there is a relationship between bullying on the job and gender if we collapse across job categories?

b. What is the odds ratio for the analysis in part a?

c. When we condition on job category is there evidence of gender differences in bullying?

d. What is the odds ratio for the analysis in part c?

e. You probably do not have the software to extend the Mantel-Haenszel test to strata containing more than a 2 3 2 contingency table. However, using standard Pearson chisquare, examine the relationship between bullying and the Job Category separately by gender. Explain the results of this analysis.
