How we handle numbers
Every stat says what it's measured against
“15 of the last 30” means nothing without the denominator and the window. Our facts carry both, our research pages show the sample size, and when a popular idea doesn't survive the data, we publish that too. The course exists so you can hold us — and everyone else — to the same standard.
