Regressionanalysis - Essay Example494). The charge mean was 0.0065, which did not support claims that males atomic number 18 better than females.The gender gap among highest performers fails to account for the differences in majors. gibe to the variance ratio (VR), the group with greater variance has more people in the tails, where math geniuses be found. Greater male variance is characterized by VR 1.0 (Hyde et al. 495). Among whites, the ratio is 1.45 for the 95th percentile and 2.06 for the 99th percentile (Hyde et al. 495). For Asian Americans they are 1.09 and 0.91 respectively. The latter shows that in the 99th percentile for Asian Americans, females exhibit higher variance. Authors explain that for a ratio of 2 for the 99th percentile, there should be 67 percent males and 33 percent females. However, they argue that PhD programs in engineering beget only 15 percent women, which is not in accordance with the mathematical abilities of women presented here.The gender gap fo r abstruse problem solving is nonexistent as well.

Lewin spent only one sentence summarizing the test results.

Lewin also expanded on the research by Hyde et al. arguing more or less SAT scores and how girls perform worse because more girls take the exam.The
