Percentage of RWU (black bars) versus PC (white bars) students who consider one of the following statements is consistent with ID: A = no opinion, B = ID is religious doctrine consistent with creationism, C = ID is a scientific alternative to evolution and of equal scientific validity among scientists, D = ID is a scientific theory about the origin and evolution of life on Earth, E = ID is not scientific but has been proposed to counter evolution based on false scientific claims. Comparisons between institutions: a biology majors (RWU n = 237, PC n = 212), Chi-square = 20.943, df = 4, P ≤ 0.001. b Nonmajors (RWU n = 239, PC n = 143), Chi-square = 10.946, df = 4, P = 0.02. c Biology freshman (RWU n = 93, PC n = 70), Chi-square = 27.152, df = 4, P ≤ 0.001. d Biology sophomore (RWU n = 74, PC n = 34), Chi-square = 35.625, df = 4, P ≤ 0.001. e Biology junior (RWU n = 33, PC n = 50), Chi-square = 16.577, df = 4, P = 0.002. f Biology senior (RWU n = 37, PC n = 58), Chi-square = 34.145, df = 4, P ≤ 0.001.
