FIGURE 3.

Bar graph comparison of SEA-PHAGES and traditional gender and ethnicity student groups on the PITS survey variables and future intent to persist in the sciences. (A) PEER male students in the SEA-PHAGES and traditional laboratory course (blue and yellow bars, respectively). (B) PEER female students in the SEA-PHAGES and traditional laboratory course (blue and yellow bars, respectively). (C) Male and female students in the SEA-PHAGES program (dark blue and orange bars, respectively). (D) Male and female students in the traditional lab (dark blue and orange bars, respectively). Equally sized random student groups by course type were propensity score matched and compared on average treatment effect on the treated (ATET). Significant differences following Holm-Bonferroni correction are indicated (*p < 0.05). PITS survey ratings are from 1 (strongly agree) to 5 (strongly disagree) for all measures except scientific community values, which had a 1 (not like me at all) to 6 (very much like me); scientific community values rating was proportionally rescaled to 1–5 for this figure.
