XKCD-Correlation.png

Three panel cartoon of a man and woman chatting. In the first panel, the man says, ''I used to think correlation implied causation.'' In the second panel, the man says, ''Then I took a statistics class. Now I don't.'' In the third panel, the woman says, ''Sounds like the class helped.'' The man shrugs and says, ''Well, maybe.''
