Bro, this video should be nominated to a Nobel Prize. It clarified me very important concepts, I think I love you. Thanks for your clarity, you are AMAZING.
THANK YOU! I hate when professors or books talk like we already know why this normal distribution exist. Very helpful!
You explain so well, thanks for this! hope to see more videos
Man !!!! I've never seen a better teacher. Absolutely BRILLIANT ! PLEASE UPLOAD MORE !!!! ❤️🙏🏻😭
I don't ever comment but I just had to, THANK YOU SO MUCH for these videos! They're saving my life right ahead my statistics final...There really is no book nor video that explains stats as understandable as this channel! :)
God bless you human.
Thank you 😇
Amazingly explained. I was always confused by Z. You explained why we need to find and use Z. Thanks
This is the real way of teaching thank you very much for your explanation .
Very informative video , you have explained everything so clearly along with graphs and diagrams , truly awesome !! thanks a bunch for the help 😊😊
thank you thousands of times,not thousands, millions. you're a life saver. keep going
Amazing explanation. the examples helped so much!
I understood your examples, thanks for breaking them down for easy comprehension.
this guy, bluebrown guy and stat quest guy is pioneer of stats/maths/ML and DL ngl!!!!
you are the best teacher on youtube. Thank you!
Thank you for helping others. Explained well.
Well done!! This has been a game changer for someone that is currently taking statistics. Thank you for putting this video together!!
great introduction vid, well explained. thank you!
Outstanding explanation. Cleared everything
Thank you for such a good explanation!
Thank you for your nice, informative and clearly explained video.
Excellently concise explanation.
That helped me alot. Thanks sir! Love from India 🇮🇳
Bloody brilliant. Am trying to teach my students stats and put them on to your site. They now understand stats.!!! Good old Aussie - congratulations on great teaching. Go the Wallabies.
Thanks for this awesome explanation dude!
You know you are awesome..n gifted the way u simplified things here....coming from a stat novice :)
perfect explanation. thank you
One of the best videos on Internet, completely cleard all my doubts, Pls make some course on Udemy, I have taken some course there, but most failed to make these concepts clear
properly.
I don't think even the founders would be able to explain it so well :) God bless ya!
That was really really really helpful. Godly explanation❤
Really easy to understand thank you so much.
Clear explanation , thanks
Thank u for this... I finally understood the logic applied
WHAT AN EXPLANATION APPRECIATED
Great explanation !!!
Why Normal Distribution is everywhere
Answer: Central limit theorem(as n increases, the distribution of the sample mean or sum approaches a normal distribution)
7:02- Converting Any Normal Distribution to Standard Normal Distribution(Where Mean=0 and Std=1)
by using z score and the value which is obtained after applying z-score is the value which will fall in the standard normal distribution
Very nice visual way of teaching. The software you are using helps to make connection between various parts of learning, when zoomed out. When zoomed out, I get the "I can see the bigger picture" feeling. This software can easily transfer to visualising subjects like history and many more.
hi bro, how are you after 6 years
Hi, Thanks for the video. It would be great if you can do an extensive video on Central Limit theorem
Brilliant! Thanks Justin. KeepSmiling 😊🐣
Very well explained!
9 years later... still saving lives. Ahead of exams that is. Still saving em' all nonetheless. This video is what it took for things to finally click for me. It was that _"a-ha!"_ moment.
if i have only the data w/o the standard deviation, how do I calculate it ?
Can you please explain how you used the table... Like what values you selected or what you subtracted or added to get that value?
Yes most needed!
Thanks, really good video!
Your content is amazing plz make some videos related to stochastics
For those wondering how we use the Z distribution table : We simply do this algebra 0.4998 (for Z being the biggest value in the table which is 3.59) - 0.4332 (Z = 1.5) = 0.0666 ~ 0,067 (I guess so... )
Thank you so much!!!
It's really great Video :)
Very clear explanation
Thank you. You're great.
Well done dood, thank u so much
sir , you are God .....the perfect explaination that's the exact thing I wanted..thank you so much❤
Simple and clear
Really helpful thanks a lot
I LOVE YOU MAN!!!!!!!
great teacher😊
We want more videos from you.
That was fucking brilliant!!
Nice teaching method
Thank You 😊
nice explanation
Thank you!!
Thank you❤
Please do lognormal distribution!
bless this man
Thanks a lot
❤
Thanks alot!!!
30th of july 2021 superb man
I find the picture of the students in the classroom at 2:02 very misleading! It has the shape of a normal curve, but it is not a normal curve. The taller students should be on the right side, not in the middle.
I was also thinking the same...
The whole idea is to correlate that as the number of students increase, the arrangement of heights tend to be a normal curve. Thus find the arrangement in line with whats being explained.
True but then how would the height variable explain normal distribution??
exacltyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy
I think the probability you found for above 190 cm height should be on the left of the line towards mean and not at the right of 190 cm line.its a mistake. It should be 1-0.067
Keep making these videos
At 4:15 explanation, did u find the probability of heads and prob of sixes using binomial distribution? i was wondering it has to be binomial if not then which?
Thank you.
Which distribution theoretically, represents the distribution of arrival rates of an event taking place.? Not sure if this is articulated well enough however i have a dataset that captures the arrival rate of unscheduled cars arrving at a garage for emergency repair. Sampling the data and plotting it on a histogram; it takes form of a normal distribution but im uncertain in my decison. Thanks for anyone who can help.
Please make a video on Weibull distribution
Thanks you

How can this distribution be used in statistics, data analytics and real life?
What are the limitations of normal distribution and how can they be circumvented?
very nice
Yes I did normal distribution. Could you teach Gamma distribution.
So the parameters are what create the distribution? What would the support of a normal distribution look like?
Yo man. The best..
Can u do a little detailed about normal distribution
@3:25
For two coin toss, total outcomes are HH, HT,TH,TT
0H = TT => 1/4 = 0.25
1H = HT,TH => 2/4 = 0.50
2 H = HH, => 1/4 = 0.25
1.5 z value = 0.933 , this is area till 1.5 or upto 190 height, we are looking for greater than 190, so the calculation is 1-0.933 = 0.067. Love you all. Peace
The data you took from he table seems corresponding to -1.5. I dont know if this is a mistake of my understanding or a overlooked mistake. Please help me to get this clarified.
Thank you in advance
i think its mistake too
thanks
did you do a video about log normal?
I don't really understand how does central limit theorem apply to the classroom example
How is SD 1 in standard normal distribution
How is it different from Binomial distribution? Every trial has 2 outcomes, getting a six and not getting a six. Every roll is independent.
Tell me exactly how you calculate the 0.067%
Nice
At 4:17 the probability of getting six (the shown value) is wrong. Isn't it? I would expect to get 1/6 and not 0.33
the probability of getting one 6 is actually 0.323. you can calculate this like that: 1. what do we want to calculate? -> the probability of getting one 6 2. how many rolls? -> 10. if you think about it, one possible scenario where we hit only one 6 could be (no = not 6, yes = 6): no, no, no, no, yes, no, no, no, no, no. now you have to calculate the probability of that scenario: (5/6)^9*(1/6) = 0.0323 (5/6)*9 because thats the probability to roll no 6 for 9 times and (1/6) for rolling one 6. but thats only one possible scenario. If you think about it, there are 10 possible scenarios with 10 rolls and only hitting a 6 once. you could roll a 6 with roll number 1 and then 9 times no 6. or you roll a 2, then a 6 and then 8 times something except a 6. so to recap there are 10 different scenarios and on scenario has the probability of 0.0323 which means: 0.0323 * 10 = 0.323
Why is the standard deviation of a normal distribution = 1?
V nice
4:20 the graphs x-axis not having exact values maybe, thanks anyway content's great
Exact values meaning?
a better resolution video and one video on CLT is requested
