Correlation is not causation. It’s important to remember that in a world where polls and statistics are often brandished as “proof” of one thing or another! The website Spurious Correlations is home to plenty of wacky graphs linking two random data sets. For example, swimming pool drownings show a pronounced correlation (66%) with the release dates of Nicholas Cage films. Want another example? Between 2000 and 2009, the divorce rate in Maine scrupulously matched margarine consumption per capita. So remember, correlation is not causation!
