Right, so when p > 0.05, they don't reject the null hypothesis... thus "we found no link". The one panel where they do find a link does read "(p < 0.05)".
Coffee Stain wrote:It looks like there's a mistake in panel two. It probably should read without the word 'green', or else it sort of contradicts the panel with the "Whoa." Threw me off for a little bit as to what the joke was.

The 2008 Christmas Special had more panels, though a lot of them were just black.
XKCD Loves the Discovery Channel had the same number of panels as this comic, and far less repetition.

Quick, someone search for secret codes!

I enjoy recursive signatures.
