Multiple Linear Regression Analysis

Multiple regression analysis of salary vs rank/step. As indicated in Table 1, the simplest model with only demographic variables shows women earn salaries that are 30% lower, Asian and URM faculty earn 23% and 9% less, respectively, compared to their colleagues who are white and male. Fifteen percent of salary variation is explained by this model. As control factors are added to the model, salary differences change significantly with women earning 11% more, Asian faculty earn 8% less, and URM faculty earn 16% more, compared to white male faculty. The percentage of salary variation explained by the model increases to 91%.
