Question K16 on the 12th Grade TIMSS Math test given to 12th graders around the world in 1995 reveals an astounding difference in math skills between the sexes in all the countries who participated. Since this was not a multiple choice question, the scores don't need to be adjusted for correct guesses, but they do need to be adjusted for the 3% error. Where 37.2% of American boys correctly answered the question, only 34.2% are known to have understood the problem, and where 16% of American girls correctly answered it, only 13% are known to have understood the problem. Thus 2.6 times as many American boys as American girls were able to demonstrate that they understood the problem. After adjustment for the 3% error, 66.5% of Swedish boys are known to have understood the problem, which per capita is almost twice as many as American boys and more than 5 times as many as American girls.
