Study of supervisor-targeted aggression. “Moonlighters”

are workers who hold two jobs at the same time. What are the factors that affect the likelihood of a moonlighting worker becoming aggressive toward his or her supervisor?

This was the research question of interest in the Journal of Applied Psychology (July 2005). Completed questionnaires were obtained from n = 105 moonlighters, and the data were used to fit several multiple- regression models for supervisor-targeted aggression score (y). Two of the models (with R2 values in parentheses) are shown in the table below.

a. Interpret the R2 values for the models.

b. Give the null and alternative hypotheses for comparing the fits of Models 1 and 2.

c. Are the two models nested? Explain.

d. The nested F-test for comparing the two models resulted in F = 42.13 and p-value 6 .001. What can you conclude from these results?

e. A third model was fit, one that hypothesizes all possible pairs of interactions between self-esteem, history of aggression, interactional injustice at primary job, and abusive supervisor at primary job. Give the equation of this model (Model 3).

f. A nested F-test to compare Models 2 and 3 resulted in p@value 7 .10. What can you conclude from this result?
