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 36% lower, Asian and URM faculty earn 5% and 42% more, respectively, compared to their colleagues who are white and male. Thirty-seven percent of salary variation is explained by this model. As control factors are added to the model, salary differences change significantly with women earning 14% more, Asian faculty earn 22% less, and URM faculty earn 2% less, compared to white male faculty. The percentage of salary variation explained by the model increases to 99%.

Progression Analysis
The progression data for all Public Health 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 at a rate that is four years faster (p=0.03). Normative progression is defined in the Progression Matrix.
