This is a true teacher. He actually explains the concepts instead of just scribbling equations on the board.
Couldn't agree more. I am hooked.
Why MIT is a top school. I love that MIT allows anyone to watch these for free.
COULD NOT AGREE MORE!!! He is truly amazing. Suddenly the Stats I did on a Data Science Coursera course start to make sense. A couple of more lectures by him and I will have everything sorted out in my mind... My God. Some lecturers just Got it and some just Don't.
I wonder how much time and effort was made to ensure every word was meaningful and carefully stated (just been through a course with a lecturer who knew his stuff but mostly winged it which was one of the biggest wastes of my time). I also noticed not a single 'um' or 'uh' which is amazing.
@@benphua Well, I noticed four "ums" or "uhs" in second 0:35 to 0:45 alone, but I agree the lecture is very clear.
The sign of a good teacher--I landed here by accident, stayed for the entire lecture, and understood all of it...

thank you Mr. Lei
Dr. Mohamed Ait Nouh you’re welcome :)
Thanks Mr. Lel
Pajeet Singh you’re welcome
Thank you Mr. Lei
Some of the best explanations of statistics I’ve heard. Does a great job of breaking down concepts.
I've never met him, but he taught me python years ago.
we should be grateful for such giving human beings.
Watching Prof. Guttah teaching is a joy. A true inspiration for those of us who also like teaching and want to do better
I came here for the Monte Carlo simulation but got unexpectedly thus far the best explanation for simple concepts like Variance or Standard Deviation
This guy is such a fantastic teacher. I would love to have him in person, thanks again for uploading the video!
Have him for ... breakfast?
@@zZE94 Ken really sounded weird ahahahha
He prolly would love have you in person too, for sure.
At the university where I studied all teachers were also fantastic teachers until the exam. Afterwards they were all a**h****.
Brilliant lecture. I can binge watch Professor John Guttag's lectures. Amazing.
What a beautiful way to explain a concept. Starts with something so simple and gradually builds up to the more complex part, also delivers the lecture in a way that even a tiny bit of boredom can't creep in.
Isn't he the most adorable teacher ever?
Great job walking your audience through the material!
this man right here is a true teacher, understands the subject topic deeply and speaks passionately
Not what I was looking for, but couldn't help but watch the entire video. Well done sir.
same
The same!
I love random walks through youtube
wanted to know what a monte carlo simulation is but I guess ill revise some stats intuition ¯\_(ツ)_/¯
@@GaoyuanFanboy123 hahaah same xD
For those looking for some visuals of how a Monte Carlo simulation works, see the second half or so of lecture 7 on Confidence Intervals.
MVP
Thanks a lot, that was what I was looking for!
Which playlist??
Thank you for share this amazing video
Great teaching style. Small number of teachers can teach such concise and clarify. I learn a lot from the great educators.
Had this same lecture in PSYCH Stats class at CofC. Learned a lot and this was fun to watch again
Wonderful professor. So casual but I believe what the students learn will stick with them forever.
he is so funny, i wish i had such professors
Thank you for this great lecture. You explain it so well. I was looking for Monte Carlo Simulation but ended up watching the whole video.
such respect for these fantastic teachers
An instructor of the highest caliber; clear explanations, projects a seemingly universal likeable and fair personality, low intensity approach. Good hire MIT!
WANTED MORE ABOUT MONTE CARLO, but he is such an amazing teacher that I got stuck anyways!!!!
Actually you are an amazing demonstrator
26:53 Great answer to make the difference between gambler's fallacy and regression to the mean clear!
I love the sense of humour of the instructor. A great lecture indeed!
00:00 Monte Carlo simulation is a method of estimating unknown quantities using inferential statistics.
06:48 Variance affects confidence in probability predictions
13:09 Law of large numbers: Expected return of fair roulette wheel is 0 over infinite spins
19:23 Understanding the Gambler's Fallacy and Regression to the Mean
25:16 Regression to the mean is a statistical phenomenon where extreme events tend to move towards the average with more samples.
31:11 Understanding variance and standard deviation for computing confidence intervals.
37:37 Understanding confidence intervals and the empirical rule
44:04 Probability distributions can be discrete or continuous, and are described by probability density functions.
Crafted by Merlin AI.
I love these old school professors. They are true masters.
For those that may be confused, he misspoke at 23:36 "taller than average" should have been "taller than the parents". In the case that parents are shorter than average, it is expected that their children will be taller than them, not taller than average.
Thanks you for being a great teacher. I really needed some background on Montecarlo.
Thanks for sharing this video. Concepts very well explained and accessible. Thank you.
The best way to explain variance formula!
I love professors who make mistakes and make corrections accepting help from students.
Great lecture. The concepts were explained clearly. I understood them very well. Thank you!
great video, such a clean delivery of the concepts. well done
Thank you Prof. Guttag & MIT.
Finally understood what statistics is about after 10 years of endeavour! Thanks so much!
Trying applying it to obtain Lebsegue Integral. See, you probably have understood nothing.
Kasra Keshavarz your face shows how stupid you are
Howard Lam. It is “Lebesgue”
Very interesting lecture, was planning on skimming it and watching small sections but I watched the whole thing without noticing the time passing!
Excellent lecture. Prof. Guttag is a great teacher. Thank you.
Every course or lecture I have watched in this MIT Open Courseware has been superb. Thank you to the teachers and to MIT for posting.
Extremely Based series of lectures. Top tier professor!
He is such a great teacher on multiple topics. After this course I plan to finally take Linear Allgebra.
Thanks for this video. Amazing explanation!
Excellent presentation. Don't know why UA-cam presented the option of the video, but watched until the end. Very gifted professor. The only thing that I can think to improve it is to repeat the question from the audience so that the question is picked up on the recording.
Makes even high level material understandable to a neophyte. That's the mark of a skilled educator.
Thank you professor Guttag. Fantastic lecture and explanations.
What a great teacher. Absolutely loved it
i love you sir. you are a great teacher.
Wow... fantastic lecture by Prof. Guttag... Thank you and congratulations.
Unfortunately, during my studies at Bachelor and Master, I never had such great real professor. Thanks so much for sharing such great video.
Hayatımdaki en iyi üniversite dersiydi.Thanks Prof J. Guttag
I really love the teachers at MIT. I have watched a ton of lectures from them and all have been great
Lies again? Support Indonesia Malaysia
Beautifully done.
The explanation is clear, his lecture is great!
After watching this lecture, I wish I was smart enough to get into such elite schools and be taught by such passionate teachers.
Respect!
But you have access to MIT open courseware
Thank you! Amazing teacher.
I had so much more fun learning the subject with Dr. Guttag than my uni professor.
What a treat to watch him teach! :) Hats off!!
Professor, your lecture was engaging. Thank you.
12:47 "win some lose some, it's all the same to me"

Suddenly the Stats I did on a Data Science Coursera course start to make sense. A couple of more lectures by him and I will have everything sorted out in my mind... My God. Some lecturers just Got it and some just Don't.
Thanks for addressing the apparent contradiction of the Gambler's Fallacy vs Regression to the Mean ~25:00 in. I'd always thought these 2 were in opposition, but guess I'd never heard (or thought of it) in the right frame of reference.
I am so grateful of your explanation
I give this professor two thumbs up. I like his style. Good presentation also. A hardy bravo zulo to the man.
Love your Data Table hack at 2'. Thank you for that!
This professor is incredible!
He is the best! Such a pleasure and luck to be able to access this lecture.
Thank you Professor Guttag and thank you late Stanislaw Ulam.
Fortunate to find his video !! A legend I was looking for !!❤️❤️❤️
that is amazing
I feel like I with no prior knowledge just intuitively already understand all of this and use it in daily life. Cool to hear it's basis though and a more technical presentation
I was excited for this one
This is the best lecture I have ever seen on statistics. It wasn't even what I was looking for but couldn't take my eyes off it till the end. Thank you Professor! Thank you MIT!
Thank you Eric.
Ok, he is really good 33:45, how I hoped to have a prof. like him back in college.
Thats the best lecture I have ever seen.
Adorei a aula, excelente!
Thanks for this video, very easy to understand
My big interest is Monte Carlo simulation and Markov chain!!!
I love a professional, whether he be a doctor or a scientist, who has the confidence and grace to admit that he makes an honest mistake.
Should of done better in highschool and went to MIT. This is great. A true teacher
A good session, I'll search for the prof and watch more videos. 👍
Amazing explanation
The true meaning of the teacher!
take care professor and thank you for lecture
Thank you , professors.
Thank you for sharing the knowledge...
proper: denoting a subset or subgroup that does not constitute the entire set or group, especially one that has more than one element.
Wow..... He truly explained what monte carlo simulation in 50 min. Thank you Prof.
+Isaac Park I've heard everything but a Monte Carlo here. Confidence intervals, regression to the mean, Gambler's Fallacy etc, but not much about Monte Karlo and its many alghorithms.
Genius teacher! Just so intuitive!! Wowwwww
Concept well explained
This is what is used to determine results of A/B testing folks, i had to learn this on the fly at my job
i love this guy
I like this professor a lot
Very good introduction of how the e-Pi-i conception of probabilistic Calculus by Pi circularity numberness/orbital is a dualistic +/- possible Infinite Sum, Normal/orthogonal self-defining "e", metastable +/- singularity convergence to zero difference, balance of frequency constants in Totality.
Great lecturer! Amazing!
Not what I was looking for, however very interesting and useful video, I will see more, thanks
what a wonderful teacher!! he teaches how to teach
I am the Great Canadian Gambler and can attest that my biggest two 6.2 Standard Deviation swings ever were back to back. Same in my early years when I played Craps to get the free junket to the casinos. Biggest win followed by biggest loss. I note that because I heard poker champ Daniel Negreanu mention the same back-to-back phenomenon. Always believed in the odds but back-to-back streaks leave an eerie feeling.
This guy is an awesome guy
Thanks!!! amazing lecture!
