Randomized Trials: The Ideal Weapon
ฝัง
- เผยแพร่เมื่อ 19 มิ.ย. 2024
- 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
Perhaps they don’t get this supposed deserved attention because their uploads are so rare?
Yes! Please don't take too long in uploading another informative animated video! (Of course, during these times it's completely understandable.)
What an amazing series of videos! It is indeed a shame they don't get enough attention
its a really really wonderful course. I have always been afraid of econometrics. Plz upload more videos soon. Eagerly waiting.
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.
Your channel is great! I really hope you guys continue uploading as frequently!
Gosh, since discovering your videos, my econometrics class feels so much more interesting.
Thank you, John Oliver of Econometrics!
With love from UK. Please upload more videos frequently. This is a great series.
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
Thank you! We're working on them. If you want to get notified when we release them go here: mru.org/mastering-econometrics

A great series, plz keep on doing it, so interesting transforming microeconometrics into easy and fun stuff.
great video!! i enjoyed to learn econometrics in a fun way. great animation too!!
Very well explained and engaging!
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.
I have just studied the paper and I will try to give some answers to this question:
1. Both groups (Control and Treatment) had the same professor. For example, if one professor taught one section of economics to the control group, he/she would teach another section of economics to the treatment group. So the problem of better teachers is not really there.
2. In the experiment the teacher could stop students from using electronic devices if he/she was highly distracted. So the negative impact of using electronic devices was put to a halt. As per proper utilization I have no idea.
Hope this answers your question somewhat.
Yes! Thanks! Amazing again.
this video convinced me to do my master dissertation on RCT in economic.
Just found out about this and I'm gutted there aren't more videos
Very nice series. Interesting
I love those videos, they are in the same style like Archer!
very high quality works
holy moly y'all have upped the production value on this one!
When is the next episode coming out?
These videos are great! Hope the one on regression comes out soon!
Hey Navid, You've told me the other day after I asked you about Mastering Metrics book, It takes me too long to follow up, but I really enjoying it now, Thanks for enlightening as you always do.
this was soooo good
No Phonesssssss! was so amzing :P
And yet : if electronics was not the norm at westpoint , then their introduction may have had an exaggerated effect. It would have been good to also test a school where electronics were the norm, and the treatment group was deprived of them, no?
Man, this is actually fun. If only this can be applied to macroeconomics
Bring out the next video soon please
It's coming very soon! Was just reviewing a rough cut last night.

This looks like Archer.
Interesting subject too.
I thought that too!

Thanks for the video(*_*)
ceteris paribus headband lmao
I guess electronic devices lower the average test scores because students did not watch this video series… I.e. you could have made already a nice reference here to external and internal validity in RCTs with a self referenceand a twinkle ;-)
lmao 7:30 "i dont get what she is talking abo..."
Actually, clear questions have to go through unclear stages first, lol.
Please don't ever stop trying to explain econometrics to dummies like me
