Understanding Uncertainty

This is a cool website Understanding Uncertainty whose mission statement is:

 

Welcome to the site that tries to make sense of chance, risk, luck, uncertainty and probability. Mathematics won’t tell us what to do, but we think that understanding the numbers can help us deal with our own uncertainty and allow us to look critically at stories in the media.

They have a number of things on there but I like an animation called Numerators and Denominators  – Visual Fraction which lets you visually show claims like “3 out of every 200 people…”

It’s fairly flexible and I hope to use it in classes soon. It’s supposed to be embeddable but I can’t get it to work. Clicking on the above link should work.
