A good professor gets down to the level of a student and stops assuming things. A great professor gets down to the level of the weakest (new to the field) student in the class and makes them feel that they are not alone. And he is an excellent professor. Thank you MIT.
You’re describing a good teacher, a good professor is the one who produces new knowledge constantly, i.e., publishes a lot of (highly cited) papers. In top universities, professors assume their audience are geniuses, so they barely explain trivial concepts and seldom provide their students with technical details. C’est la vie
@@RealGigaMind precisely, that's the point. If you receive just great minds, you don't have to produce them. This explains why admission into top universities, in every country, is quite hard. You're missing the point, Professors don't aim to be good teachers but to be good researchers. The college system is designed in such a way: publish or perish instead of teaching as much as you can. Someone with a high publication record has a better chance of being hired at any University than another candidate with a lower record although the latter is a better teacher. Perhaps, in the foreseeable future, AI will produce great minds instead of natural intelligence hehe. Teaching could be the sort of job, where AI might replace its human counterpart.

This course should be the standard for every statistics across all levels in education. My current statistics course in community colleg is structured ineffectively and goes straight into the math. While this applies a lot more real word situations & lore that makes the class exciting.
I had to take a stats class as a requirement for my Admin Justice major..after I took this class and achieved in it just by sheer trying hard and studying..I was able to get an A and decided to try science and engineering courses and I did pretty good because I got Fs in HS when I took them. So I thought I'd settle for a career with less education requirement after HS--20 years later I'm a software engineer for a major telahealth company. I'd never would expect this--I thought I'd be a cop
The expectation that I was "bad at math" led me away from pursuing a STEM degree when I graduated high-school. Ten years later I discovered that I was not bad at math, I was just a lazy student and that I might need to put in effort. I hate to think how many people are in the same boat.

"Statistics is about replacing expectations with averages ... everytimes you see an expectation you replace it by an average" this resume all this lecture.
Not really. The classification of dropping your iphone as a non-random occurrence is dangerously naïve considering is just proves the person making the claim has no true understanding of what randomness is. Literally at the quantum level the uncertainly rule prevails. Therefore Everything we do a random mathematical computation of XOR.
PERSONAL NOTES 1. Say p = 60% from n samples. How many samples would it guarantee that p > 50%? We need a model for this. The goal for our model is that the density must be as narrow as possible (least possible volatility), and the value that we're looking for is as close as it is likely to be. Assumptions: random (good way to model lack of infos, otherwise non-math wouldd suffice), i.i.d,
Lecture aside, I just wanna say that the course structure of 30% assignments, 2x 15% midterms and a 40% Final is very smart. Looks like grading is more focused on learning throughout the semester to engage the students. Courses with 50% Final and 2x 25% midterms or similar does not do anything to help students learn in the long term. Great class structure
in my country the final is 100% of your grade and you need to pass two midterms to be allowed to have a go at the final. Such an insane system my country has lol
it depends on the side we sleep on, take average of a persons sleeping side, there will be a natural tilt already because of that. also right hand gives more control and balance.
Loved that you captured your audience with the "kissing Statue" in relation to stats..... very engaging :) since statistics in a Phd program is so painful lol

I took stats 35 years ago, and worked as a statistician for a decade before switching to medical translation. I am interested now in my retirement to see how much I remember.
@@astudent8475 I switched because the medical info data-processing company I worked at moved way across the city and would have added another hour's commute each way. We also had two small kids in daycare and translation is something I can do from a home office. As I am an expat American, there was a niche for a medical/pharmaceutical native-English speaking translator. My wife worked at a pharmaceutical company designing clinical trials, and these require reams of documents to be sent to regulatory agencies in the EU and USA, primarily. It was much harder for her to withdraw to child-care duties than it was for me. I quite enjoyed the dad role, and didn't really miss company culture. Satisfied?🍻😉
At 30:00 - It doesn't matter wether you go with with Alice or Bob. They should be getting the same amount of money, as the number of dots greater than or equal to 3 has 4/6 sides of the dice covered (3, 4, 5 and 6 -> 4/6 -> 2/3). Am I mistaken?
38:33 I feel this is the best ad for people thinking of becoming a statistician, you get to play in everybody's backyard! AND grill them for information in their field! It's like exclusive access that you're paid to have 🤣
Hi, relative to undergraduate curriculum, would this be considered Intermediate Statistics / Statistics II, following an intro-level college stats class? Thanks!
There are X logical statements that explains Y algebra is useful to learn in science and tech; and Y it can be used to do N things in life, for any kinds of operation that 1 can care to image, including the use of imaginary numbers for complex tasks themselves. It is all about integration and the sequences that have to be followed to achieve equality and reason in all of knowledge, so that we can have the opportunity to be the greatest at numeration and denomition as well as domination of those lessor; for X > Y when X have more knowledge then Y. Y? Because of Z!
There are no problem solutions available for this version of the course. You might want to look at the 2015 version. It has problem sets with solutions: ocw.mit.edu/courses/18-443-statistics-for-applications-spring-2015/. We hope this helps. Best wishes on your studies!
Me too from India. Too much competition here for IITs and top private colleges are just too costly. And on top of that, I already have completed my Engineering. Myself Ali Shabbir Hussain.
I don't understand, when rolling 2 dice, the number 7 is the most likely to happen? The students agreed as well as the prof. agreed to that! I though all numbers have the same probability, of course considering the dice to be balanced, no cheating. I feel stupid! 30:50
I am also learning, but here is my understanding, 2 is the minimum number as total of 2 dices, and 12 is the maximum. (2+12) / 2 =14/2 = 7. In other words, to create 7 , the combination can be (1,6) (6,1) (2,5) (5,2) (3,4) (4,3) and we have 6 pairs to create 7. Other numbers, for example 8 , we cannot use 1 in either of dice, as we cannot create 8 if one of the dice is 1, another dice cannot be more than 6 . To create 8 (2,6)(6,2)(3,5)(5,3)(4,4) so we have 5 pairs. If we continue to count pairs for other numbers, I think we can understand that 7 is the number which we can create more pairs than others.
Could someone please illustrate how the 7 has the most high probability for the problem at 31:00 Chose a number between 2 and 12 Win 100$ if you chose the sum of the 2 dice. I didn't quite understand how its 7
There are 36 ways to get a total. Only one way to get a total of 2, which is double 1. But there are six ways to get a total of 7, which is the maximum number of ways for any particular total, and so this is the most likely total.
I really need indepth statistical knowledge for applications from a Proficient Tutor even if it's within a short period of time as I can learn anything fast if I am serious and really interested. Not all these confusion they're giving us in school.
Where can I find the equation used in the last example, so I can understand exactly what each letter and placement means etc? Without that info, I got lost rather quickly in fully grasping it.. thanks 🙏🏼 I want to do a few similar problems so I can understand.. 😅

truly a great intro to statistics. by the way, the variance estimator of gaussian is a biased one, I think [1/(N-1)] ∑(xi - µ)^2 would be a better choice

Statistics are about knowing the distribution of the entire poppulation given the distribution of one dataset
Thank you Liam Neeson
Most of the people don't know that,Statistics is a subject of Science.🇧🇩🇧🇩🇧🇩 But we can't think any sectors that, where Statistics aren’t use.Thanks a lot for your explanation.
Charting and statement are possibilities in realizing models.
I took stats 35 years ago, and worked as a statistician for a decade before switching to medical translation. I am interested now in my retirement to see how much I remember.
@@astudent8475
I switched because the medical info data-processing company I worked at moved way across the city and would have added another hour's commute each way. We also had two small kids in daycare and translation is something I can do from a home office. As I am an expat American, there was a niche for a medical/pharmaceutical native-English speaking translator. My wife worked at a pharmaceutical company designing clinical trials, and these require reams of documents to be sent to regulatory agencies in the EU and USA, primarily. It was much harder for her to withdraw to child-care duties than it was for me. I quite enjoyed the dad role, and didn't really miss company culture.
Satisfied?🍻😉
Is this the same as introduction to statistics for economists???
"Biased" is the word that u were looking for :)
I also guess the same but it May be sample bias
yep. i guessed the same
Replace expected value with average, --> statistics.
This class kicked my ass.. ok bye before commercials end 🏃♀️
Gotta read that article on kissing so I can better understand statistics...
MIT is King. Period.
This course would have been much better if the course site actually has solution for us to compare our answer with.
Lecture starts at 13:20
Thx a lot
Going through a tough time, I hope things get better
It will man it will
At 30:00 - It doesn't matter wether you go with with Alice or Bob. They should be getting the same amount of money, as the number of dots greater than or equal to 3 has 4/6 sides of the dice covered (3, 4, 5 and 6 -> 4/6 -> 2/3). Am I mistaken?
Could you provide the solutions to the assignments and recitation materials?
arent they in their website?
38:33 I feel this is the best ad for people thinking of becoming a statistician, you get to play in everybody's backyard! AND grill them for information in their field! It's like exclusive access that you're paid to have 🤣
I am not in the class but I still watched the first 13:20 minutes
Hi, relative to undergraduate curriculum, would this be considered Intermediate Statistics / Statistics II, following an intro-level college stats class? Thanks!
Yes, it would be. See the Math Major Roadmaps for details: math.mit.edu/academics/undergrad/roadmaps.php. Best wishes on your studies!
There are X logical statements that explains Y algebra is useful to learn in science and tech; and Y it can be used to do N things in life, for any kinds of operation that 1 can care to image, including the use of imaginary numbers for complex tasks themselves. It is all about integration and the sequences that have to be followed to achieve equality and reason in all of knowledge, so that we can have the opportunity to be the greatest at numeration and denomition as well as domination of those lessor; for X > Y when X have more knowledge then Y. Y? Because of Z!
Great lectures and problem sets. But is it possible to get related solutions? Or is any one working with problem sets? Plz contact me!
There are no problem solutions available for this version of the course. You might want to look at the 2015 version. It has problem sets with solutions: ocw.mit.edu/courses/18-443-statistics-for-applications-spring-2015/. We hope this helps. Best wishes on your studies!
please post the course for introduction to probability! :D thank you for the videos btw!

This is a good one from Harvard
@@atrijitdas1704 thank you!
about couples, what if x is male and y is female. and male control the position. and x isnt changing and y is changing.
Are the samples really independent? The 2 59s, they probably impacted.
Lecturer :"i am actually tend to speak faster , so I hope y'all understand"
Me : play in 2x speed

Watching from Bangladesh, there is no way I will not have access to such a goldmine, living such Poor country .
Me too from India. Too much competition here for IITs and top private colleges are just too costly. And on top of that, I already have completed my Engineering.

I don't understand, when rolling 2 dice, the number 7 is the most likely to happen? The students agreed as well as the prof. agreed to that! I though all numbers have the same probability, of course considering the dice to be balanced, no cheating. I feel stupid! 30:50
I am also learning, but here is my understanding, 2 is the minimum number as total of 2 dices, and 12 is the maximum. (2+12) / 2 =14/2 = 7.
In other words, to create 7 , the combination can be (1,6) (6,1) (2,5) (5,2) (3,4) (4,3) and we have 6 pairs to create 7.
Other numbers, for example 8 , we cannot use 1 in either of dice, as we cannot create 8 if one of the dice is 1, another dice cannot be more than 6 .
To create 8 (2,6)(6,2)(3,5)(5,3)(4,4) so we have 5 pairs. If we continue to count pairs for other numbers, I think we can understand that 7 is the number which we can create more pairs than others.
Could someone please illustrate how the 7 has the most high probability for the problem at 31:00
Chose a number between 2 and 12
Win 100$ if you chose the sum of the 2 dice.
I didn't quite understand how its 7
Nevermind. I understood.
Most numbers add upto 7
i also confused at fist and then i realize 7 has the most combination than other numbers
There are 36 ways to get a total.
Only one way to get a total of 2, which is double 1.
But there are six ways to get a total of 7, which is the maximum number of ways for any particular total, and so this is the most likely total.
I really need indepth statistical knowledge for applications from a Proficient Tutor even if it's within a short period of time as I can learn anything fast if I am serious and really interested. Not all these confusion they're giving us in school.

Why do we have to use statistics in genetics
Milla Rita coz gene follow statistics
1:10:29
X_i follows gaussian(or normal) distribution
Please record mathematical statistics 18.655, thanks!
👏👏👏congratulations from Brazil for the class !
Where can the problem set of 30 questions that he mentioned be found?
The lecturer is awesome.
Where can I find the equation used in the last example, so I can understand exactly what each letter and placement means etc? Without that info, I got lost rather quickly in fully grasping it.. thanks 🙏🏼 I want to do a few similar problems so I can understand.. 😅
You can find the lecture notes on MIT OpenCourseWare at: ocw.mit.edu/courses/18-650-statistics-for-applications-fall-2016/.
Best wishes on your studies!
@@mitocw thank you!🙏 ☺️
Could you add Lecture 10 and 16 from this year (2017)?
If I am reading the tea leaves correctly, those lectures are the in class exams, so no real material is missing.
Video starts at 13:00
Just must use stat with wordly evens.
At 23:00 why would reusing data for different questions lead to wrongful conclusion ?
Mit you do not have to use digitized voice system to make your point !!!
Is there a change to get access to the mandatory lessons? Thanks for sharing the course!
Thank You
Education without politics
What Software does Prof. Rigollet use to make these slides?
I guess it's RMarkdown but can someone confirm?
Looks like Latex with Beamer package.
Maybe it is posible put subtitles spanish, gracias.
Am I the only one who laughs at his jokes? Just me? The class attendants seem dead.
Please record your introductry number theory lectures
truly a great intro to statistics. by the way, the variance estimator of gaussian is a biased one, I think [1/(N-1)] ∑(xi - µ)^2 would be a better choice
Any supplementary material recommendations? I found this course is a lil hard to follow
We recommend you check out the course prerequisites listed in the syllabus, "Prerequisites
Probability theory at the level of 18.440 Probability and Random Variables. Some linear algebra (matrices, vectors, eigenvalues)."

@@mitocwThanks a lot :)
Can we find the solutions for the problem sets?
Sorry, the instructor did not give solutions to the problem sets. Maybe some kind soul has them posted somewhere.
