STATS 60 tests an artificially intelligent robot TA

As part of a three-week pilot study this quarter, half of the students in STATS 60: "Introduction to Statistical Methods" were assigned a RoboTA, an artificially intelligent robot teaching assistant (TA), to answer their questions by email. Students emailed different addresses based on the TA they were assigned. The emails were then funneled through a program, stripped of any identifying information and relayed to Lucas Janson, the TA for the class. Janson replied to all the emails without knowing whether they were intended for the human TA or the artificial intelligence (AI) TA. This study is double-blind, so neither the students nor the experimenters have information about the other, which helps prevent bias.
