Posts Tagged ‘Correlation’

Boing Boing‘s Cory Doctorow¬†reported on a spurious correlation of nearly 1.0 between autism and organic-food sales discovered by Jasonp55 on Skeptic Reddit.

This inspired me to look for other extremely high (albeit spurious) correlations with autism. I discovered a correlation of 0.994 between college costs (tuition + fees) and autism rates between the years 1999 and 2007, inclusive.

In the article that I’m certain to get published in Science, my main conclusion will be this: if we want to slash autism rates, we’ll need to drastically reduce college costs by returning educational funding to the levels of previous decades.

Here’s a graph of the cumulative percentages of the two variables that shows clearly their close association.
