Delivered casually, while bringing out subtle points very sharply. By far the most lucid explanation I've seen. Thanks for taking the time to make the video and for giving it to the world for free!

Ngl, that first question was hard for me. I had to attentively watch the solution to get a solid understanding of the concept. But then the second question became a breeze for me once I familiarized myself with the underlying statistical ideas. Feel much more confident about my knowledge of Hypothesis Testing now.

Thanks for making such high-quality content! Really appreciate it :)

One of the best channels ❣️ i enjoy learning from your videos. Thank you so much 🙏😇

[MightyFineMoran]

I can clearly see your ability and understanding of how to present these concepts in a digestible way. You are fantastic at your job :)

[juliecongress]

You actually make me like statistics! I appreciate the explanations with the very understandable examples.

Thank you, your videos have helped change my life!

At 22:57, why is the standard error just sqrt(var(theta)) and not sqrt(var(theta)/n)?

[dustiinde]

Thank you! can I ask you which software you are using to show your slides. I know that zooming can be done using Ms. Powerpoint, however not all possible.

at 25:54 why you chose to use pooled proportion BUT
at 35:25 you did not use pooled proportion?
I used
θ ÷ sqrt(p1q1/n1 + p0q0/n0)
as my test statistic
which leads me to t=2.009868
is that okay as well?

[skylerjohnson]

the examples really opened my eyes on statistics, very well done!

great video and illustration. I really like the big map and putting all the details in one long video, very comprehensive and saved my time of finding all short scattered video.

Only halfway through this video but this video is really helpful for getting an intuitive understanding of the concepts for hypothesis testing. Thank you!!

At 39:29, you say confidence interval crosses zero because p=0.58 is greater than 0.05. Could you clarify how to infer it crosses zero if calculated p value is greater than 0.05 ?

[MymaiTps]

Amazing videos!!! You have made all the statistics concepts easy to digest and understand! Thanks a lot and please keep it up!!!
P.S: just found out that your videos are being used as our lecture recording... WOWWW...

[CheshtaBeniwal]

Awesome video :) Couldn't wrap my head around why is the variation of the red and black distribution different in the second exercise? Please advise if possible, thanks

[luisrodrigueziii]

Hello sir. Why does theta have to equal "p1-p0=0" ? If they both subtract to give 0, then why can't one say: "p1=po"? Are different formulas used between these two ways to describe the null hypothesis?

[shuangqili]

If my stat teacher can teach 10% as clearly as in this video...

[ado]

@ 22:58 why on earth the variance divided by the variance squared should be equal to 1??

[mahbubulhasan]

Are you using Prezi making these videos? Or May I know what tool u used to make your videos? TIA
