Thanks for all of these very helpful videos. Calm and clear explanation! The internet needs more great people like you.

[@nitameha9025]

Thank you very much. I was studying policy and impact evaluation in Switzerland, and it was hard to understand this Law.
now, with your explanation it's clear.
I hope it helps me for the exam :D

[@johncharles3907]

So easy to understand when you explain it. Thanks man!

[@boladauuluitavuki7440]

Thank you. Makes perfect sense now.

Hi, glad to hear it helped! Best, Ben

[@inchicago]

At around 2:48 you say that taking an expectation of an expectation is essentially summing over all the values which the variable sex can take on. Is it really though? Isn't it more accurate to say that it's summing over all the values which E[IQ | Sex] can take on (by the definition of expectation). It appears you are missing a crucial step and I don't want to immediately accept that that it is just the same as summing over all the values for which sex can take on.

So just a weighted average of sub-populations, said in a fancy way!? That's how I got it. Thanks for explaining it in simple terms!

[@jacobm7026]

Brillian work, Ben. We appreciate you!

[@xinglinli9874]

Finally get the intuition behind it, thank you so much

[@maryamzolnoori1621]

[@ZiyiZhang-b8j]

Nice explanation! Better than my college lecturer!🎉😂

[@ishitadeb6361]

thank you so much, now the concept is much clearer

[@patiwatatayagul8738]

This is pretty clean and clear.

[@luisvictoria]

I don't understand the very last bit, aren't you supposed to take a second expectation of both male and female populations after summing their expectations together?

[@jordanjohnson9591]

That was an absolutely beautiful explanation. Thank you!

[@AloofMusician]

Amazing explanation.

[@User_forbidden]

This just confirms everything.

[@rodrigo10239]

Great explanation! Thank you very much!

[@JarJarBings123]

That is a beautiful explanation. But I did not understand why E(E(X/Y)) has to be the sum of Y's.
