TABLE 5.
Discipline summary statistics for opportunity gaps as measured by ΔNRR for all undergraduate course sections (n = 3207). Results for ΔNRR (Approach #3) are given for each demographic characteristic examined. The mean and standard error are provided for the opportunity gaps from each discipline. The overall F-test and respective p-values for the test of the difference across disciplines. Significant results are denoted with an asterisk (*)
