Finally, someone was able to explain the chi square test in plain English...
You are so good at teaching. You make everything so clear in such less time than other videos. Thank you so much!!!
you're getting me through my entire schooling career. In high school I used your videos and now in my third year of university I still find myself coming back to your videos for help. You're one of the best Instructors on the planet.

same this guy got me through high school and helping me out in college too! it's great!
I never, or rarely comment on youtube videos of people teaching something, but I've been using a lot of your content to try to understand the basics of stats and probabilities, and your content is simply awesome. Really good explanations, voice is clear and friendly, you give the student the will to learn and it's really awesome. Keep it up ! Love from Paris
I NEVER comment on youtube videos, but this helped me so much, and I finally am beginning to understand what's happening! You are more appreciated than you could ever know.
I'm in a research course in grad school and am barely staying afloat, mostly because the instructors and materials just throw a wall of jargon at us with, apparently, the expectation that learning these concepts would happen either magically or by osmosis or something. It's like they're trying to teach us a foreign language by giving us books written in that language and then flunking us for not being able to do literary criticism in that language after a week. It's ridiculous. I've got multiple degrees, speak multiple languages, have worked around the world, but they act like we're dumb because instead of teaching, they just expect that what seems obvious to them will be obvious to everybody. This one video is the only resource I've found that breaks it down to a level accessible to those not already part of the "in-group" of trained statisticians. THANK YOU. Is it really that hard to just say, this is what it is, this is what it's for, and this is a quick look at how it works? EVERY other resource I've found either gets lost in this self-referential loop of jargon being explained with jargon; or else it takes 3 hours to explain what could be said in 2 minutes. I've subscribed and will probably spend my study hours here instead of with the useless course materials I was provided.

Wow that's harsh, I hope you're alright now.
A little bit of a nitpick, you said at one point "we accept the null hypothesis." I am not incredible at stats but I do know that you can NEVER accept the null, you can only reject or fail to reject it.

You accept or fail to accept. There's nothing like rejection.
I love how you teach, you make everything so simple and easy to understand.
I am taking Graduate Statistics right now through an online course and this gave me better insight than any material provided by the school so far. You also did it in a fraction of the time in comparison to other videos in a way that made sense. I'll be following for future videos. Thank you.

Graduate statistics? I learned this in my intro to statistics class…
This is such a helpful video! You spoke clearly and slow enough for me to be able to understand. Thank you so much!!
Another exam session and another marathon of your films. Thanks!
What a nice way to teach statistics especially bisecting the technical terms to understandable form.
this guy saved my ass every night before my exam since I was in middle school until now I am a senior :) thank you dude !
Wow. Finally someone goes through the entire process. Thank you!
YOU ARE MY HEROOOOOOOOOOOOO. YOU LEGIT MADE IT SO EASY TO UNDERSTAND. KZread IS SO UNDERRATED
Best I watched so far . Thanks ❤️💎
to understand the basics of a concept that I knew absolutely nothing about in 6 minutes is amazing 😭tysm, i owe you my grades
Thank you so much. Your teaching is spectacular
i learn more from this man than all my lecturers combined...
Our teached assigned us four videos (each half an hour long) to explain everything you just did. Thank you
F man, you make things so easy to understand. What a teaching ability!

Thank you! I was struggling to understand the concept in class, but you explained it very well!
I love your content. your voice is relaxing. ❤ you made everything so clear and natural.
been trying so hard to understand this until ur video popped up in my feed. so much thanks for you sir!
THANK YOU! I had to watch it a few times, but I understand it now. Thank you for explaining it in layman's terms.
Sir you wonder your tutorial is very beneficial to me. I can't just stop watching and downloading them
thank you so much you are literally the saviour of all the students Imagine sleeping at night knowing that you are saving the lives of all the students around the world
Props to this guy👏👏👏👏 I cannot imagine learning all this without his help😁
you got me through O Chem I and II in undergrad. I'm now in my second year of med school and we meet again. Thank you for being amazing!
Good and simple explanation of Chi Square. Thank you.
Your explanations are so much clearer than my units at university, thank you. Also, has anyone told you that you sound just like Mark Whalberg!

Clear to understand videos. Appreciate explaining many of the prob, stats concepts, problems. Do you have a video for Anova
TYSM! I'm so confused about my calculations, and you cleared my doubt. I'm having a headache since morning. I have a dissertation to submit, and this hypothesis thing is troubling me. Thank god, I can finally understand it.
Hello! Nice video! I wish to know can we use Chi-square to test the significant difference between 2 categorical variables? Since as I know that chi-square tests the association between the 2 categorical variables not the significant difference between them...is it true?
the fact that you use laser pointer on the table shows how much you care THANK YOU
I am benefiting more from this site, thank you.
great. just in few minits got the whole idea behind the test. thank you :D
damn it man you made the entire thing so easy! thanks 😭🙏🏼
it's a good one! thanks for putting it out, really helpful!
Thank you so much! finally understood the Chi^2 test!!
Thnx a lot for Making the videos. It really helps in Ecotrix and your voice is something that is also suitable for storytelling or ASMR.
Thank you , you are the best teacher 👏👏🥳
This actually popped back up again when i needed to start applying this in my next psych stats class i am so grateful

Simple, to the point!
This was awesome. I understood it in one viewing. Gracias Organic chemistry tutor.
Well explained ! Thanks !
Thank you, this is very clear
Explained succinctly
STAIGHT TO THE POINT SIR. MANY THANKS , GREETINGS FROM ZIMBABWE
Thank you so very much. It does help me alot
Amazing lecture 🙋♂️
Neat explanation! Thanks
Than u very much sir ... U change my life in a good way
you changed my life
please sir cover the Anova as well.......thanks for your contribution though.....respect
Thanks your video was quite helpful
Oh my goodness I wish my professors explained things even half as good as this video did in 6 minutes!
Can you show how the Chi Square table or distribution is derived?
the tutorial was so good and simplified, it helped me alot
got my stats finals later and you just saved my life 😭
Your explanation is too good .
So helpful, thank you
Omg uiu make it so clear and simple I wish you were my teacher❤
Really good man!
Well explained Thank you
Thanks so much for your not-so-fast speed, simple example and clear explanation
I really love you My long distance teacher, special thanks for your special explaining 🤍
Hopefully this reaches someone that can answer my question- where does the df table come from? or is that table a standard table that can be used throughout statistics?
Great video! One correction though... around 6:10 you state that we will accept the null hypothesis, but it is important to distinguish that we NEVER accept the null hypothesis, we only fail to reject it.
U r boss man U r saving my grade
Very nice thank you soo much..
Thank you very much sir... Buh what if the 'E' has different values?
Very Helpful 😊
What a teaching ability
you really are a lifesaver
THANK YOU MASTER
Love You, Thank You
Simple and clear
Thank you✨ it is helpful
bro you are better at teaching than professors
what happens if our calculated chi square value became equal to the critical point??
Let say we reject the null hypothesis. Is there a way to determine which of the categories are statistically different and which are the same? Thank you for the response.
Thanks!
How do you get the pooled value of chi squares of multiple experiments, say for instance 3 experiments? The null Hypothesis, degrees of freedom, and critical value?
@xXxIMMORTALxXx

You don't get the pooled value in Chi-square test. You would do that in comparing two proportions test because you don't know the true proportions but you have to hypothesize about them, hence you pool the proportion so that you have a bench mark value when you calculate for SE.
Doing gods work
Thank you Sir!!!
DUUUUDE TYSM 🐐🐐🐐🐐🐐
Here the principal expecting whether it is equal then the are null hypothesis should be unequal frequency right? I can't able to understand how to find null and alternate hypothesis, it's confusing.
thank you so much bro
THANK YOU 🙏🏾
Wow... Thq so much...
