what's the vertical axis? percentage difference from average test score? I mean, the chart tracks median household income (was about $60K in 2017) very closely. average income, average test scores. the correlation is interesting. not sure if the difference is small.

huh, I should be in the -60 to -40 bracket based on that chart. Makes me wonder what the mean, median, and mode is on that chart. Would have been better if they displayed it as a cat-and-whisker. Why am I such an outlier?

Source of that chart seems to be talking about how even after trying to make changes to it, they can't seem to shake the affluence factor. Odd that there are two equally viable interpretations of the same data. https://blogs.wsj.com/economics/2014/10/07/sat-scores-and-income-inequality-how-wealthier-kids-rank-higher/ …
