Simpson's Paradox

Su questo video

Thanks to https://brilliant.org/minutephysics for sponsoring this video! This video is about Simpson's paradox, a statistical paradox and ecological fallacy where seemingly contradictory results are implied by a single set of data depending on how it's grouped. The paradox can arise in medical studies, student test scores, and so on.
