Preintervention Salary among Treatment Group, by Participation Status
Salary was measured on June 1, 2016 (N = 3,257). The six bins were defined to include 25%, 25%, 25%, 15%, 5%, and 5% of employees not screened, respectively. The null hypothesis of the Pearson’s chi-squared and the nonparametric Kolmogorov-Smirnov tests is that the two samples are drawn from the same distribution.
