Graphing just the test scores showed Texas with significantly worse scores. Then he showed them broken out by race and for every race Texas had better test scores for any given race.
I don't know if there's something I'm just not understanding here, but I don't see how it's possible to have higher scores in every subcategory without having higher scores in the combined category.
Without examining the data, I can't verify, but it could work out like this:
Wisconsin: 60% North European, 20% West European, 20% Hispanic
Average North European score: 100
Average West European score: 100
Average Hispanic score: 80
Wisconsin Average: 96
Texas: 20% North European, 30% West European, 50% Hispanic
Average North European score: 105
Average West European score: 105
Average Hispanic score: 85
Texas Average: 95

Ah, interesting, okay. Now that I see numbers it does make a lot of sense.
