MattW writes "A few days Slashdot reported is no gender difference in math performance. Alex Tabarrok, posting on Marginal Revolution, notes that it all depends on what you mean by gap. He writes that the Wall Street journal reported the findings correctly: boys and girls have the same averages, but boys are more likely to both excel strongly or fail miserably. Quoting from the study, Tabarrok notes that for every measured grade, VR (Variance Ratio) is higher. So while the average between genders is the same, the pool of potential candidates for an extremely high level of aptitude has more men than women because of the higher variance."
