I work for a company that collects aggregated SAT data. I was pretty upset when I discovered there is a very strong, direct correlation between family income and SAT score, with a credible spread of several hundred points between the average scores of the highest and lowest income groups. I knew that there would be a correlation, but seeing how strong it was was pretty depressing.
