this is amazing , thank you so much
The world is still exists because of people like you. Thanks a ton for this lecture. God bless you.
no she is sellinng her course and book
@@Adiishresthaaa whatever might be her intentions this course has helped me a lot
@@Adiishresthaaa Yes, of course, she wants to sell her book, but I think it's ok, almost everybody wants to profit from his/her knowledge... I'd buy the book.
As a matter of fact, I already bought the book and it is an excellent book by the way, it is helping so much in my university studies.
@@Adiishresthaaa So? Why should she deprive herself of what she rightfully deserves?
It is something very special that you have created to educate us. Absolutely Great Efforts. Thank you very much.
It's my pleasure! Many thanks for your nice feedback! Regards, Hannah
@@datatab Muchas gracias por tanto esfuerzo para nosotros aprender mas, DIOS te bendiga y te guarde de todo mal, bendiciones amiga.
@@juangs1168 Many thanks for your nice feedback!
@@datatab Hi mam,can you please share which video has explaination regarding Complete Random Block Design...I have seen most of your videos but couldn't find this topic! Please shed some light upon this!
Thanks
@@munchkin98phd17 We do not have a specific video for this! But it is very similar to a two way ANOVA except that a block is used instead of the second factor.
I just compelted less than 4 minutes of the entire 4 hours video and found that I'm already in love with the trainers explanation, classification of learning and the courage she gave before hand. I love this and will watch for the NeXT 2 years in my M.Sc (Applied Statistics). More comments on the fly. I love Statistics.
Splendid, I'll save this video in my playlist and share it with friends.
My plan 30 mins per day till I digest and understand all statistics
❤❤
Greate : ) Thanks!
@@datatab Haven't watched the video and I'm not a numbers guy. I'm just asking for my kid. Can this video be of any learning benefit to an 12 year old.
The lecture was really very organized, and it even seemed that every single item of information had been put in place with great thought. What's more, the high level of engagement has captured viewers by making difficult concepts easily apprehensible, thus encouraging active participation. Thank You!
Many many thanks for your nice feedback!!! Regards Hannah
Das ist ein ganz ganz tolles Video. Ich nehme gerade meinen ersten Statistik Kurs in Psych und war endlos verzweifels. Danke vielmals.

That is a good point! We will put it on our to do list!
This is wonderful thanks, I'm going to enjoy in half hour chunks also - I'm a physics teacher but I am enjoying being reminded about this content. By the way what do you use for your graphics they are super? I would like to do a similar thing for making physics revision videos for my students.
Thank you so much for this!! Super helpful. Love from India❤
Many thanks for your nice feedback!!!!
Great video 👍🏻
Thank you so much.
Hello, Dear, I joined your channel recently and your videos are helpful for statistics. I love your brief description with great examples and clear explanations.
But now I want to ask one question and I hope, you will clarify it. The question is "What is the difference between multivariable and multivariate analysis".
Brilliant as usual ❤
Many thanks : ) Regards Hannah
Hi DATAtab your explanation is good & Nice.
Very thankful
Excellent .
You teach better than my professors at my university
Informative videos
Thank you for this tutorial
You're welcome 😊 Thanks and Regards, Hannah
🔴 Well done and keep it up! You deserve a like and another subscriber! 👍👏
Thanks for the sub and your nice feedback!!! Regards Hannah
well done !
Thank you...just bought the book.
Many many thanks!!! Regards Hannah
I am trying to get into data science with R programming and I found your video so far great and highly informative. Do you have a future plan to make videos about data science in detail such as probability, machine learning, data visualization and etc thanks. I'm Yehualashet from Ethiopia.
thank you for this
Amazing course
I'm glad you like it
epic video, I will be binch watching soon 🙂
Vielen Dank Thomas : ) LG
Thank you so much. O wish you were my teacher in school.
Super video, thanks fof compacting all in one place.. By he way.... you should add: "Papa Taxi", as a means of trasportation to get to school...
This is too good to be true!
This lecture clearly is for non mathematicians. In the last century I learned all this in school, but even with mathematical proofs which were all left out here.
Wow thanks alotttt
thanks a lot.
Great!!!!🎉🎉
Thank you! 😃 Regards Hannah
You should do one course for how to use Stats in Finance & specially in understanding markets.
DESCRIPTIVE AND INFERENTIAL STATS EXPLAINED IN FULL
Thank you for making stats this simple, how can I perform Fisher exact test using this software.
Hi many thanks for your feebdack! To perform Fisher exact test you need to click on "Hypothesis test" and then select two nominal variables with 2 categories each. Regards Hannah
You are great thanks
So nice of you! Regards Hannah
Thank you so much
You're most welcome
This is an excellent video. Thank you.
I wish to get the book, but inaccessible from my country due to credit card ops!
Oh sorry! But most of the content you can also find at our tutorial section. Have a look here: datatab.net/tutorial/descriptive-inferential-statistics
@@datatab Thank you very much for this.
@@ibrahimlawan9663 You are welcome : )
Ого, невероятно понятно, спасибо
The hypothesis testing and confidence intervals that we estimate from a sample and generalize to a population is an inductive process. However, the internal procedure of these statistical processes is deductive, as we make several assumptions and then deduce our conclusions, right?
روعه 😮❤❤
this is an invaluable youtube channel for student!
Many thanks!
Wow..... This is pretty deep dive.
Not all super heroes wear capes. This right here is a super girl of statistics
: ) Thanks : )
