...As usual, we point out that correlation does not imply causality, but simply points to associations between variables. Still, a number of interesting things stand out.
It should come as little surprise that states with higher levels of obesity have significantly higher rates of death from cancer, heart disease, and cerebrovascular diseases like hypertension. There is a significant correlation between obesity and death rates from cancer (.7), heart disease (.7), and cerebrovascular disease (.7)."
