It’s been a loooonnnnggg time since I studied graphs. It is not adjusted for relative size of each cohort but rather just tries to show where each scatter peaks out. Does that make any sense?

I think most division is based on socioeconomics, and not so much race.

The Journal of Blacks in Higher Education: The Widening Racial Scoring Gap on the SAT College Admissions Test

But there is a major flaw in the thesis that income differences explain the racial gap. Consider these three observable facts from The College Board's 2005 data on the SAT:

• Whites from families with incomes of less than $10,000 had a mean SAT score of 993. This is 129 points higher than the national mean for all blacks.

• Whites from families with incomes below $10,000 had a mean SAT test score that was 61 points higher than blacks whose families had incomes of between $80,000 and $100,000.

• Blacks from families with incomes of more than $100,000 had a mean SAT score that was 85 points below the mean score for whites from all income levels, 139 points below the mean score of whites from families at the same income level, and 10 points below the average score of white students from families whose income was less than $10,000.

This was also noted in the book "The Bell Curve". One presumes that black families with middle class incomes have access to good nutrition

Not really, because I’m not too familiar with graph terms. Apparently you believe that it explains the perfect symmetry of the graph. I’ll have to lookup your terms. Thanks for the answer. :)
