The Definition of Sufficient Statistic Looks Weird (a 2 minute remake)

One of my most popular videos, remade and half as long.
The idea took me a long while to decipher, and once I did, it turned out to be simple! So I made the original of this video to spare you the same grief, and I recorded this remake to improve the quality. Enjoy!
