Finally, someone was able to explain the chi square test in plain English...
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.
My uni should pay him my tuitions lol
Same here
don't know why tf I'm paying thousands of dollars to Uni and felt like they teach us as if they don't know a way to make it easier to understand. Literally throw everything at once
same this guy got me through high school and helping me out in college too! it's great!
@@giapham5944 couldn't agree more
You are so good at teaching. You make everything so clear in such less time than other videos. Thank you so much!!!
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
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.
who cares
@@ratdad6021 anyone trying to get full credit in an exam..
@@ratdad6021 like they said, it’s a nitpick.
@@ratdad6021graders
You accept or fail to accept. There's nothing like rejection.
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.
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.
Another exam session and another marathon of your films. Thanks!
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…
Grasped a concept in 6:43 mins, 18 mins before my exam, what my prof couldn't in 40 mins, God bless you mate!
how did it go
@@SBImNotWritingMyNameHere passed with flying colours
F man, you make things so easy to understand. What a teaching ability!
stats final?
@@toastedsniper9248 yep
@@piyushanejacs21 hope you did well on yours 🙏
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 !
I love how you teach, you make everything so simple and easy to understand.
to understand the basics of a concept that I knew absolutely nothing about in 6 minutes is amazing 😭tysm, i owe you my grades
This is such a helpful video! You spoke clearly and slow enough for me to be able to understand. Thank you so much!!
YOU ARE MY HEROOOOOOOOOOOOO. YOU LEGIT MADE IT SO EASY TO UNDERSTAND. RUclips IS SO UNDERRATED
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!
I just came to say this!! I keep picturing him teaching statistics! lol
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
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
What a nice way to teach statistics especially bisecting the technical terms to understandable form.
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!
been trying so hard to understand this until ur video popped up in my feed. so much thanks for you sir!
the fact that you use laser pointer on the table shows how much you care THANK YOU
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.
THANK YOU! I had to watch it a few times, but I understand it now. Thank you for explaining it in layman's terms.
Thank you! I was struggling to understand the concept in class, but you explained it very well!
Been learning from your videos for my modules Statistics, Biology, Chemistry... Thank you so much ❤
Best I watched so far . Thanks ❤️💎
This actually popped back up again when i needed to start applying this in my next psych stats class i am so grateful
Best of luck ✨.
So it goes?
@@mohsinbaig2195 thanks!
bro you are better at teaching than professors
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.
Wow. Finally someone goes through the entire process. Thank you!
Oh my goodness I wish my professors explained things even half as good as this video did in 6 minutes!
Thank you so much. Your teaching is spectacular
damn it man you made the entire thing so easy! thanks 😭🙏🏼
Sir you wonder
your tutorial is very beneficial to me. I can't just stop watching and downloading them
Thank you for the video! I enjoyed absence of unrelated information!
Good and simple explanation of Chi Square. Thank you.
Props to this guy👏👏👏👏 I cannot imagine learning all this without his help😁
got my stats finals later and you just saved my life 😭
I love your content. your voice is relaxing. ❤ you made everything so clear and natural.
This was awesome. I understood it in one viewing. Gracias Organic chemistry tutor.
I really love you My long distance teacher, special thanks for your special explaining 🤍
OMG! OVER A MILLION SUBS. I'm so proud! I've been here since ~200k
this is so easy to understand!! thank youuu
Omg uiu make it so clear and simple I wish you were my teacher❤
great. just in few minits got the whole idea behind the test. thank you :D
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.
saving me in middle school , high school now in uni take a bow
Thank you , you are the best teacher 👏👏🥳
My teacher says we fail to reject rather than accept
Ur teacher is an idiot!
you changed my life
This is simple way clearing any ambitious
Your explanation is too good .
Thanks so much for your not-so-fast speed, simple example and clear explanation
Thank you so much! finally understood the Chi^2 test!!
Explained succinctly
please sir cover the Anova as well.......thanks for your contribution though.....respect
U r boss man
U r saving my grade
STAIGHT TO THE POINT SIR. MANY THANKS , GREETINGS FROM ZIMBABWE
Your teaching is so clear! Thanks a lot 🙏🏾🙏🏾🙏🏾
Clear to understand videos. Appreciate explaining many of the prob, stats concepts, problems. Do you have a video for Anova
DUUUUDE TYSM 🐐🐐🐐🐐🐐
What a teaching ability
i fucking love you, you deserve all the love in this world
I am benefiting more from this site, thank you.
the tutorial was so good and simplified, it helped me alot
it's a good one! thanks for putting it out, really helpful!
Interesting example. A quick visual inspection of the data would lead me to believe that frequencies are unequal. But they are not, based on this test.
I'm not joking or kidding when I say this, my proffesor to 2 weeks to explain the chi-square test. Here, you only took 6 minutes. how and why??? Idk, thank you for your help
you really are a lifesaver
Great work as always
Thanks your video was quite helpful
Can you make a video on analysis of variance?
Can you show how the Chi Square table or distribution is derived?
Well explained
Thank you
Thank you, this is very clear
Than u very much sir ... U change my life in a good way
Well explained ! Thanks !
Thank you so very much. It does help me alot
THANK YOU MASTER
Thanks!
Thank you for this video. Very clear and straight forward. I have a question, given your example, is a Chi Square analysis appropriate for examining this problem? This is what I mean. For the practical needs of the principal in your problem, if weekly absences regularly reflect a well curve, this is important practical information. That is, for the practical purposes of the principal, this would be deemed significant, even if those absences only fluctuate by a relatively small percentage.
Simple and clear
So helpful, thank you
Very nice thank you soo much..
Great video .. very clear ! Thanks
Simple, to the point!
Very Helpful 😊
Doing gods work
Degree of freedom = (rows - 1)* (Columns-1) = (2-1) * (5-1) = 4
Thank you✨ it is helpful
Amazing lecture 🙋♂️
As usual he is the best 😂
Really good man!
I should pay some of my fees to this channel imo
I wish it was this simple in genetics....
Love You, Thank You
