What if we have different number of people in the two groups? How do I calculate this?

wrong formula. where is the degree of freedom in the denominator?

thank you so much!

has it changed to SE =1/sqrtn-2 instead of n-3

excellent！

Why not label the hinge and fences...

From about 3:14 to 4:10, the margin of error has mu_M when it should be sigma_M.

Sounds very technical. Not at all user friendly. Consider researchers who need to use this information, but are not statisticians or math people. This is not our primary language. It needs a more human explanation.

Excellent!!! I’m a stats nerd BUT it’s been forever since I needed to calculate a t-test!!! THANKS for the outstanding refresher!!!!!

I do not think that statistics may be the single most important subject matter I study.

Thank you. Best video

ok

if the n between the two samples is different, is it averaged as well when calculating the estimated standart error of the difference?

Still no voice over! Sigh...

Thank you! Using this for Psychology Statistics Class.

Adult men comprise with HIV in South Africa. In 2016, an estimated 104 000 [101 000-110 000] adult men acquired HIV, representing 39.2% of all adult infections in South Africa. There has been a 26% decline in new HIV infections among adult men since 2010.

I attended an interview with FAANG for a data science position & I was asked these statistics questions I am still thinking if my answer is right or wrong. What is the right answer for this problem? Question: What is the base rate of conversion for mobile versus desktop sites? Total no of customers: 590381 Out of 590381, the Total no of customers that were converted: 701 These customers used mobile or desktop sites Total no of customers using mobile: 269400 No of customers that were converted using mobile: 507 Total no of customers using the desktop site: 320981 No of customers converted using the desktop site: 194 What is the base rate of conversion for mobile versus desktop sites? My answer was 0.18819599109131405 & 0.060439 after dividing 507/269400 & 194/320981, but the interviewer was not convinced.. If the base rate means should I divide 507 / 590381?

Yes the slides do not match with the narration

I was learning so much from the video, and he just had to remind me that Bill Gates has criminally more money than I do and will ever have. :'(''

Thanks

19 squared is equal to 361

Ooooh.... I see pascals triangle!

this is a great explanation although you need to know a bit of stats already

Great video, thank you for it. After a regression is performed and I have the estimate of the parameters (say a, b, and c), I would like to calculate some some call "the standard deviation" of the parameter for each parameter. It is allegedly a measure of how meaningful the parameter is. Any idea how I can calculate that? And, is that the same thing as the "bivariant"? - I hope you can help me - thanks

what the fuck happened to the comment section?

Great work ! Thanks 🙏🏻

I am curious about the history or origin of using the random variable Z in the standard normal distribution.

The Script is all here onlinestatbook.com/2/analysis_of_variance/within-subjects.html

This is a horrible example .

Poor explanation !

I want to understand how the table fisher's z-values is used.

:)
