Percentage of RWU (black bars) versus PC (white bars) students who agree with one of the following statements concerning their own education: A = I prefer science courses where evolution is discussed comprehensively and humans are part of it, B = I prefer science courses where plant and animal evolution is discussed but not human evolution, C = do not know enough to say. Comparisons between institutions: a biology majors (RWU n = 237, PC n = 212), Chi-square = 1.543, df = 2, P = 0.46. b Nonmajors (RWU n = 239, PC n = 143), Chi-square = 3.723, df = 2, P = 0.15. c Biology freshman (RWU n = 93, PC n = 70), Chi-square = 3.953, df = 1, P = 1.0. d Biology sophomore (RWU n = 74, PC n = 34), Chi-square = 9.389, df = 1, P = 0.002; asterisk indicates sign test two-tail pairwise comparison P ≤ 0.05. e Biology junior (RWU n = 33, PC n = 50), Chi-square = 0.105, df = 1, P = 0.74. f Biology senior (RWU n = 37, PC n = 58), Chi-square = 2.082, df = 1, P = 1.0. Combined freshman, sophomore, junior, and senior responders (mean of RWU + PC) for A vs. B differ in c to f, sign test two-tail P ≤ 0.05
