Marc:
"Marc, would it be possible to get percent white or percent black compositions for these districts?"
I'll do better than that.
You didn't.
He asked a really simple question that didn't require such a long response, and besides he asked for statistical data and you gave him an emotional diatribe. Perhaps I need to read it again, but I couldn't glean the information he was asking for from what you responded. If it's there, it certainly isn't obvious or simple to understand.
It's also clear from your last post that you didn't understand what Mike was saying. I'm beginning to believe, actually, that you have a non-rational, non-linear, emotional/visual mode of thinking and aren't at your best in dealing with logical or statistical arguments. (And if that's the case, then I owe you a personal apology for assuming in the past that you were being deliberately deceptive.)
Anyway, what Mike was saying was that funding is only one factor behind educational performance. He was also saying that the demographics of the student body (average intelligence, background, etc.) is important in determing how well a school performs. This, of course, is outside the control of the school and no amount of improvement or reform in the methods used to teach children will affect it.
Finally, he was arguing that a better way than absolute outcome to measure school performance is to measure improvement from beginning to ending test scores of students.
So he wasn't saying, as you suggest, that all we need to do is give the schools more money. And therefore addressing that idea does not address what he said.
