[quote=Anonymous][quote=Anonymous][quote=Anonymous]I have now spent a couple hours plotting GS data points on a graph.  According to what I have so far:

1-there is a direct inverse relationship between the GS score and the percentage of black and hispanic students at the school.
2-there is a direct correlation between the percentage of white and asian students (added together) and the GS score.
3-there is a direct inverse relationship between a school's diversity and the GS score - in other words, schools with a student body that has large numbers of every racial group, as opposed to being dominated by just a few, are actually penalized in the GS scoring system.
4-having a less diverse body raises the GS score.  This seems to be true even if the school is 80% of a traditionally lower-performing minority, as it is the diversity itself that lowers the school's score (since the school is penalized for having gaps between races).

I don't have every school in Fairfax County on there, of course, but I have quite a few and it seems high GS scores indicate not only lack of low-income students, but also ensure lack of racial diversity.  Barring AAP centers, which are artificially balanced, no school with a 9 has any significant percentage of black or hispanic students.[/quote]

Sherlock, did it ever enter into your mind that these schools are in fact better? And that schools with larger number of blacks are not as high performing?[/quote]

The problem is not the usual problem with test scores representing demographics, and black students being disproportionately impoverished.  There seems to be an actual weighting against schools with racial diversity as a result only of the diversity and not of actual overall performance.
