[@restlesscrow4680]

perfect timing! Im working on a Stats Machine Learning project right now, hah.

[@julianvelez6563]

Awesome work ❤❤

[@rachitsingh4913]

Now this is what i was looking for❤️ thankyouuuu

[@brandon_wallace]

Excellent video.

[@chaitanyamundle7]

Amazing course. The only question I have is at 2:21:14, you got the CI = [0.4, 0.426]. However, when calculating the practical significance, you used the CI[0] = 0.04 instead of 0.4 while comparing it with Delta. Won't this fluctuate the result? And prove our result to be "Not practically significant" ?

[@yanyan7782]

Yeah, I see the same problem here. The calculated CI is different with the CI used in the practical significance function. The initial code was right so there was no need to change." lower_bound_CI >= delta". To prove practical significance, the lower bound of CI should be higher than delta. That means that even the lower bound of the confidence interval of the delta is higher than the MDE, so practically should proceed with the treatment design.

Shouldn't in the case study for alternate hypothesis ue > un instead of equal to so we conduct only one side test.

Can you provide CSV File and Colab Notebook?

[@Zerocoolgdjdgevsj]

Yes please

[@yeomxi]

Can someone please let me know if someone new to Python can also learn this course? Do we have any prerequisites?

[@LunarTech_ai]

Hi there, in this Course basic Python is a prerequisite - please check of our "Python for Beginners" free KZbin course

Hi sir fan your teaching in app development

[@museumofplaylists]

Data is the new oil.

(Confirm on essential)

[@wah866sky7]

Would you please share the code for this A/B Test Tutorial ? Thanks

[@zhufaryasykur8678]

where is the demo csv files??

[@ojasvisingh786]

👏👏

[@coff3andprograming]

Seria genial que implementen una app con django y ciencia de datos ❤

[@TechWithKate]

30+ motorola ads in one video 😭

[@deniz-gunay]

too many advertisement..

[@howardsmith4128]

Where is the Colab Notebook and CSV file. Without it the course is almost useless.

[@GoatzAreEpic]

I wouldn't say AB testing is advanced statistics. more like introductory

[@adityajds1816]

pronunciation of every word is very confusing other wise it would have been a great video

[@newmanokereafor2368]

@adityajds respect people’s nature, distinct cultural and linguistic differences as everyone didn’t emanate from your geographical area. She gave out so many information for free, yet you are majoring in the minor.

[@sushmitamukherjee673]

@@newmanokereafor2368 he did not disrespect, simply stating it was confusing for him. Accents can be confusing, kindly bzz off.

[@ozan4702]

Any tutorial involving coding without the repo is useless
