This document discusses Simpson's paradox, which is a phenomenon where data can show one trend overall but a different or even opposite trend when broken down into subgroups. It provides a definition of Simpson's paradox and shares a link to a Brookings article that discusses examples of this paradox in education and earnings data. The document encourages visiting additional resources on the thinkteachtalk.net website to learn more about Simpson's paradox and see a related video presentation.
