Concept explainers
Study of supervisor-targeted aggression. “Moonlighters” are workers who hold two jobs at the same time. What are the factors that impact the likelihood of a moonlighting worker becoming aggressive toward his/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-directed aggression score (y). Two of the models (with R2 -values in parentheses) are given below:
(R2 − .101)
(R2 − .555)
- a. Interpret the R2 -values for the models
- b. 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 <.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 et primary job Give the equation of this model (model 3)
- f. A nested F-test to compare models 2 and 3 resulted 1n a p-value > .10. What can you conclude from this result?
