Dec 12 '11

Via Cosma in “comments at the other place I hang out”:http://crookedtimber.org/2011/12/11/fun-with-statistics/#comment-391599, “this”:http://www.google.com/trends/correlate/draw is a very nice teaching tool for the sole and single purpose of getting this point across to students. NB that you need to be logged into a Google ID to use it. My favorite so far is the .8222 correlation between my random graph and searches for “frogsex” (the mind squirbles).
