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

It's a shame your uploads are so rare and don't get attention they deserve

[jvb]

Yes! Please don't take too long in uploading another informative animated video! (Of course, during these times it's completely understandable.)

[azmilenario]

What an amazing series of videos! It is indeed a shame they don't get enough attention

[MarginalRevolutionUniversity]

This is the fourth video in our Mastering Econometrics course.

[ektasrivastava]

its a really really wonderful course. I have always been afraid of econometrics. Plz upload more videos soon. Eagerly waiting.

[Valorian]

Gosh, since discovering your videos, my econometrics class feels so much more interesting.
Thank you, John Oliver of Econometrics!

[emilybackets]

A great series, plz keep on doing it, so interesting transforming microeconometrics into easy and fun stuff.

[study_with_freya]

Very informative and interesting, thank you for sharing knowledge.

All of the videos in the playlist deserve 100 million likes.😊

These are golden☆☆☆ I can't wait for the next 4 or so videos.. have read two of his econometrics books... big fan of master Joshway.. waiting for regression discontinuity :) cheers

With love from UK. Please upload more videos frequently. This is a great series.

[ashishdsilva]

What a Video!! This series seems some what like Randomised Trials, Takes a lot of time and money. Well done guys. Hopefully the next video comes out faster.

[patodlmm]

Your channel is great! I really hope you guys continue uploading as frequently!

this video convinced me to do my master dissertation on RCT in economic.

I didn't read the study, but from watching this there might be two problems:
1. Maybe the control group was thaught by better teachers
2. Since the starting point for both students and teachers in the control group probably had little prior experience with using electronics in class, they might not have utilized them to their full potential or they where distracted by new things that might get boring over time and thus loose their negative effect. Running this experiment somwhere where the default is the use of electronics might give different results.

These videos are great! Hope the one on regression comes out soon!

[Altoids]

Just found out about this and I'm gutted there aren't more videos

[RoxasTheMaster]

I love those videos, they are in the same style like Archer!

[makarimmuhammad]

great video!! i enjoyed to learn econometrics in a fun way. great animation too!!

[ekananda]

Man, this is actually fun. If only this can be applied to macroeconomics

[aok]

holy moly y'all have upped the production value on this one!
