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 14% lower, Asian and URM faculty earn 4%, compared to their colleagues who are white and male. Two percent of salary variation is explained by this model. As control factors are added to the model, salary differences change with women and Asian faculty earning 3% more, and URM faculty earn 1% less, compared to white male faculty. The percentage of salary variation explained by the model increases to 92%.
The progression data for all Physical Sciences 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 gender when compared to white male faculty. URM faculty, however, progress approximately four and a half years slower (p=0.01). Normative progression is defined in the Progression Matrix.
