Ladder Rank Salary Data
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 25% lower, Asian and URM faculty earn 3% and 2% more, respectively, compared to their colleagues who are white and male. Seven percent of salary variation is explained by this model. As control factors are added to the model, salary differences change with women earning 3% more, Asian faculty earn 2% less, and URM faculty earn 3% more, compared to white male faculty. The percentage of salary variation explained by the model increases to 97%.
The progression data for all Arts Ladder Rank Faculty, are plotted below. Normative progression is defined in the Progression Matrix.
Progress Rate Analysis
The results indicate there isn’t a statistically significant difference in progression rate means by either gender or ethnicity when compared to white male faculty, indicating there is no evidence of biases against promotion. Normative progression is defined in the Progression Matrix.
