It has been a really long time since I've posted on here. I've recently been looking at the data for the SAT test. There are some pretty interesting trends as far as which states take the SAT more and which don't take it very much. You'll also note that some states have much higher SAT scores than other states. Part of the reason for this is that in the states where fewer students take the test, they tend to be the better students taking it, so you end up with high SAT scores. It is helpful to look at a map of SAT results to help sort through these trends. I have linked to one here to make some of the results I have just mentioned clearer to understand.
