Very good book , if you get chance check it out. Economist pretty much breaks down a bunch stuff from everyday life, statistically. Stuff like comparing what real estate agents sell their house for compared to what they sell other peoples houses for, why lots of crack dealers live with their parents, what factors seem to effect childrens acedemic achievements the most.
the article on teaching the monkeys to buy stuff is kind of interesting http://www.freakonomics.com/times0605col.php
