I just uploaded a new video to my YouTube channel: Probability Distributions -- Part 1 (of 3): What They Are. Part 2 will be about How They Are Used, and Part 3 will be Which to Use When. At some point, I will probably do videos on each of the 8 families of Distributions mentioned in this video. You can always see the Videos page on this website for the latest status.
