Website highlights the difference between correlation and causation

Correlated things aren’t necessarily related to each other. In other words, correlation doesn’t imply causation – and a website highlights just that. publishes a lot of apparently correlated things, which obviously have nothing in common, like for example US spending on science, space, and technology and Suicides by hanging, strangulation and suffocation.


There’s a 0.992082 correlation between the two, but of course, they aren’t connected in any way. But hey, there are even better examples – how about comparing the evolution between Number people who drowned by falling into a swimming-pool and Number of films Nicolas Cage appeared in:


Still not convinced? Let’s have a look at how the Age of Miss America correlates with Murders by steam, hot vapours and hot objects:


So there you have it people – correlation and causation are two different things, don’t draw any conclusions causation based on correlation alone!

Andrei's background is in geophysics, and he's been fascinated by it ever since he was a child. Feeling that there is a gap between scientists and the general audience, he started ZME Science -- and the results are what you see today.
