WEEK 7: MULTIPLE REGRESSION VARIABLES
22 unread replies.1919 replies.
Research has found that completing an ethical course in school or business significantly predicts more ethical behavior. In addition to how many ethical courses were taken, the study also included the independent variables of gender, age, and certain personality characteristics. Ethical behavior was based on answers to next steps based on vignettes that did not have an obvious ethical outcome. How might this study be improved, and what other variables could be considered?
