In October 2012 HarvardX, through edX, offered its first two online courses. One of these was called PH207X: Health in Numbers. The course covered biostatistics and epidemiology at an introductory level and lasted 12 weeks. 60,000 students later we had exposed more students to those disciplines than we could have over the next 250 years of typical brick and mortar teaching. Of course we had to have a statistical package, and we chose Stata. This talk will cover some of what we learned from the experience.
