If you use the dropdown to go to New York and checkout NYC, your conclusion would be that all NYC students are unjustly funded and have much less than everyone else. But.... that makes no sense. New York City has some of the best public schools in the country.

No, your conclusion, going by the coloring on the map, would not be that "all NYC students are unjustly funded". But rather, that "On average, NYC students are underfunded compared to the statewide average."

Do you understand the distinction?

Yes, exactly! And yet, the schools are still really, really good!

Partially it's because the analysis is at the county level, and not at the district level. But I'd argue that using "averages" in the first place is extremely lossy and a classic Stats 101 mistake.

This is a particularly weird statement to make in regard to NYC school performance, across the board.
