TABLE 4.

95% CIs for the opportunity gap between subgroups as measured by ΔNRR for all undergraduate course sections (n = 3207). The interval estimates for the differences in the NRRs (ΔNRR, Approach #3) are adjusted for previous academic performance. The 95% CIs show the range of plausible values for the opportunity gaps; since none of the intervals contain zero, all represent differences in opportunity gaps for each of the subgroups that are significant at the α = 0.05 level
