Correlation Doesn't Imply Causation

Tyler Vigen is posting graphs he labels "spurious correlations." They're two completely unrelated pieces of data that just happen to be parallel:
Cheese Consumption correlates to Death by Bedsheet Entanglement
Age of Miss America correlates to Murders by Steam/Hot Vapors/Heated Objects
U.S. spending on Science, Space, and Technology correlates to Suicides by Hanging/Strangulation/Suffocation
Swimming Pool Drownings correlates to Number of Movies with Nicolas Cage
We often need more than just two pieces of data to make wise and logical conclusions. The truth is frequently more complex and intuitive than simply looking at pieces of quantitative statistics. As you likely know, 87% of statistics are completely made up.
