Lecture Videos on Replicability and p-values, and Preregistration

These lecture videos are from the web, one on replicability and p-values and the second on preregistration. Thanks to three former undergrad TAs - Danielle Nebril, Kayla Grutkowski, and Dan Lehr, for finding these videos, and helping to come up with the questions!
