Curious Correlations: Cheese and Bedsheets, Divorce and Margarine
A common statistics mistake is to assume that two trend lines that look the same (that is, are correlated) implies a cause-and-effect at work. As you’ll see from the interesting and amusing correlations from Tyler Vigen’s Spurious Correlations, nothing could be further from the truth. See how total arcade revenue is correlated to the number of computer science doctorates awarded in the U.S. and how drownings after falling out of a fishing boat are correlated to the marriage rate in Kentucky.
