Now look at the coorelation of income to test scores. The higher your income, the more likely that you will be able to take SAT prep courses, attand private schools etc.
The discrepancy between male and female scores is likely due to the speed vs. sustained reading portion of the exam, and the multiple choice format. Both favor a males ability to visualize spatial relationships while failing to give credit for a female's ability to sustain read and form cognitive opinions.
