These are just a few interesting statistics on the different achievement levels and comparisons between boys and girls.
Not only do males average 35 points higher on the Math portion (and 4 points higher on the Verbal), but the disparity grows as the test challenge becomes more rigorous. Males account for 60% of those who score over 600 on the SAT Math, and the ratio of males to females in the top 0.1% of mathematical ability ranges between 7 to 1 and 14 to 1 The source of this duality is that males have greater "variance" on all manner of cognitive tests. That is, they are dispersed more widely all over the map of psychological testing, high and low, while girls occupy the more moderate middle-ground. According to an analysis of sex differences in mental test scores in Science (7 July 1995), males have a greater variance than females of between 3% and 15%, and the variability is especially striking in certain areas such as mathematics or spatial reasoning. Technically, boys have a greater standard deviation. Although boys score higher on standardized tests, girls receive better grades in all disciplines. The average 11th grade boy writes at the same level as the average 8th grade girl! Only 17% of bachelor's degrees in engineering and 35% in math and science went to women. On the NAEP (National Assessment on Education Progress) males outperform females, with more males than females scoring at the proficient or advanced levels. The percentage of girls who say they like science from 4th to 8th to 12th grade, goes from 66% to 47% to 48% (Educational Equity of Girls and Women, National Center) The percentage of girls who believe that anyone can do
well in math if they try declines from 90% to 71% to 46%, from grades 4, to 8,
to 12 (Educational Equity of Girls and Women, National Center for Education
Statistics, 2000).
