statistics: US States Schools Ranking

An interesting example of statistical data analysis and visualizations.
NJ is ranked 3rd in both measured rankings (quality & safety), but it is overall 2nd :)
First map chart displays only one dimension.
Also check small print on meaning of "safety", it is quite limited.

This reminds me of textbook for statistics, How to Lie with Statistics
that is now available online free, on both & Google Books. 
It is likely out of copyright, since it was first published in 1954.
It even has a page turner and a voice reader!

As the author of the book suggests, those who present data already know the tricks.
It is the rest of people who can benefit from learning how to spot them.
