Percentage of biology majors (black bars) versus nonmajors (white bars) 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 within institutions: a RWU biology majors (n = 237) versus nonmajors (n = 239), Chi-square = 4.808, df = 2, P = 0.09. b PC biology majors (n = 212) versus nonmajors (n = 143), Chi-square = 2.485, df = 2, P = 0.28. c RWU within-biology-majors comparisons: F = freshman (n = 93), So = sophomore (n = 74), J = junior (n = 33), Sr = senior (n = 37), Chi-square = 13.676, df = 6, P = 0.03; linear regression choice A: r = 0.75, P = 0.24, choice B: r = 0.79, P = 0.21. d PC within biology-majors comparisons: F = freshman (n = 70), So = sophomore (n = 34), J = junior (n = 50), Sr = senior (n = 58), Chi-square = 11.702, df = 3, P = 0.008; linear regression choice A: r = 0.74, P = 0.25, choice B: r = 0.74, P = 0.25
