Randomized Trials: The Ideal Weapon

MIT’s Josh Angrist—aka Master Joshway—introduces us to our most powerful weapon: randomized trials! Randomized trials originate in medical research, where they’re called “randomized clinical trials” or “RCTs.” That’s why randomized trials are said to measure “treatment effects”. Josh covers a fascinating study from West Point that seeks to answer a common question using randomized trials: Are our devices more distracting than useful when it comes to learning? In this video, we cover the following: -What's the difference between control and treatment groups? -How to "check for balance" -The Law of Large Numbers -Treatment effects -Standard errors and statistical significance **INSTRUCTOR RESOURCES** High school teacher resources: https://bit.ly/2RcCsta Professor resources: https://bit.ly/2XgdHQG Econometrics test bank: https://mru.io/o94 EconInbox: https://bit.ly/2yzTjzz **MORE LEARNING** Try out our practice questions: https://bit.ly/2xVuvSg See the full course: https://bit.ly/2Xc88CQ Receive updates when we release new videos: https://bit.ly/2VaLTdH More from Marginal Revolution University: https://bit.ly/39QeWZo
