Spurious correlations: an engine for head-scratching coincidences


The Spurious Correlations engine helps you discover bizarre and delightful spurious correlations, and collects some of the most remarkable ones. For example, Per capita consumption of sour cream (US) correlates with Motorcycle riders killed in noncollision transport accident at the astounding rate of 0.916391. Meanwhile, but exploring the engine, I've discovered a surprising correlation between the Age of Miss America and Murders by steam, hot vapours and hot objects (a whopping 0.870127!).
