Hello sir.. I must say u r one of those on RUclips who actually knows the real definition of random variable and made all my concpets very clear ... I have seen amny videos from prominent coaching institutes but all fail miserable to expalin this simple idea .. thank h very much sir ..
You are my hero and you confirmed my suspicions that a random variable is a misnomer for a very familiar concept in algebra we call a function. Even calling that function random is regression to the misnomer! You explained it very well and your explanation deserves award and recognition within the statisticians’ cult. Thank you so much! That’s what happens when people from outside the math community force themselves upon the masters and come up with weird nonstandard notations that ultimately confuse the very logic and tradition of mathematicians!
Thanks. My students also appreciate this approach and they have done extremely well. I am glad that you and many, worldwide, also like. Thanks once again.
Awesomevideo! This gave me a clear picture of random variable. Since I have understood it, I don't think I will ever forget it. The flow of the topics and your explanation is simply amazing. Great job.
thank you so mush sir..!!! honestly I was searching for this concept ..i opened and closed so many videos becz i was unable to understand ..fortunately i came across ur channel...understood really well :) :)
By definition a function takes at least one input and provides an output.. I don’t see how a random variable takes an input and provides any output that you chose to call it a function.. It is random because it can assume multiple values X = 0,1,2,3 etc and each value can be assumed with a probability attached to it .. For normal variables you don’t have probability attached .. Normal variables will assume a value ( finite or infinite ) but the question of certainty is not attached to it ..
Sir the session is amazing 👌 sir can you make a video about difference between continuous and discrete random variable to make the concept crystal clear
Great explanation except for the first question and its answer which I disagree. True, a random variable is a function from the sample space to the set of real numbers. Thus it takes as inputs elements of the sample space which are as a result of a random experiment. So these elements ( the results of the experiment)are not only varied but they are the outcomes of a random experiment. Therefore the associated real numbers, that is, the outputs (more than one number) of a function whose inputs are varied and random are necessarily random. When we say X is a random variable we mean X takes on different values (the variable part) which represent the results of a random experiment (random part).
It is random and variable. It "random" because the value taken by the random variable depends on what is the outcome & remember that the outcome of the random experiment is random. It is a "variable" in the sense that it depends on what is the outcome. In the experiment of tossing a coin twice, the outcomes can be any one of {HH,HT,TH,TT}, if we define X is random variable indicating number of heads, the value of X depends on the outcome which is random (In the sense outcome could be anyone the 4 possibles & we know only after its occurrence). And this the reasons for my argument. The remaining part is explained neatly.
Yess!! it is random n variable Random because u can take wht ever the function u want defined on sample space and for every function u will get random outcome And variable because image associated with every function varies

One thing I like most about you sir is the calmness in your lecture which portrays a higher understanding of the mathematical concepts. Then I also like your methodology. You have a great calling in this profession.
I really get inspired and motivated by your lectures each time I listen to them. Whatever topic I am looking for, I make sure to watch at least one of your videos to fully understand the concept. Thank you sir for the inspiration and knowledge I get from your lectures.

13:20 Collection of heights is discrete. Discrete means they are fixed values and not vague regions. If I say my height is anywhere between 6 and 7 meters, that could be continuous case. A similar term to discrete is stochastic.
My vision after watching this video : R. V. Is a function and is also a variable Function Bcz we can have condition on the way we want our outcomes & Variables Bcz the outcome values are different for different elements of sample space Plzzz correct me if I am wrong 🙏🙏
Thanks a lot for appreciation. I am trying to develop a website and organise the video for efficient use by the students. I will appreciate if you could post something there along with your picture.

This was a very good video and linking random variables to functions was helpful to understand the concept. Thank you!

So crazy! I've had trouble understanding the concept of random variables. Helpful to realize that random variables are neither random nor variables.
Thanks, That is what I like most about this randomness!
.I appreciate you for this video, you so descriptive
He did not explain why it is not RANDOM why It is not Variable??

i was having a lot of trouble with these concepts; this video was super super helpful. thank you for posting this 🙏
I proud the teacher like u .i could not understand statistics i am little bit weak but your vlog help me alot .its clear my all concepts
U r the real teacher
I am very grateful. Thank you so much for sharing this knowledge. Truly incredbile.
thanks sir
You are a really good teacher . Thanks
thank you so mush sir..!!! honestly I was searching for this concept ..i opened and closed so many videos becz i was unable to understand ..fortunately i came across ur channel...understood really well :) :)
you are more the amazing teacher and your examples are very useful but i wishes that you but the whole course on youtube
My wish too. That would be great indeed.
Really very helpful and easy to understand. Thank you sir.
great explanation

Excellent explanation!!!!
good understanding thanks a lot sir anil kumar
Thanks for this video 🤠
Quite confusing concept but explained better in this video. It's a hard concept to easily understand. It requires much concentration.
Thanks for sharing
Very good 🙏😊🙏
Method of speaking is clear .. I like it.
Thanks
I like it too. It shows much competence in the work done.
Excellent explanation...excellent

Random because u can take wht ever the function u want defined on sample space and for every function u will get random outcome
And variable because image associated with every function varies
@ Smurthy A u r right
I could not understand this in class, your vlog has helped me understand more about random variable

Very clear ,usefull ..sir kindly explain *count the number of heads n tails when a single coin tossed 10 times without throwing a coin*
Thanks for the excellent question. I will post the video soon.

good sir. i understand by your lecture
You're a godsend sir. My professor should stick to his research bullshit.
Thank you so much 😊 I wish my lecturer to be you

I also had doubts in understanding those..

R. V. Is a function and is also a variable
Function Bcz we can have condition on the way we want our outcomes &
Variables Bcz the outcome values are different for different elements of sample space
Plzzz correct me if I am wrong 🙏🙏
the vary first line of this video was not less than any dialogue ....
it was just amazing to hear...

Sure sir I will
If X is a random variable and c is any constant, can we say (cX)w=cX(w) where w is a element of samples space?
thankuuuu sir!
thank you, i understand now 😄

Thanks, sir
Good work sir
Thanks for appreciation.
nice sir
can you understand what you are saying. you are saying one word 10^(infinity) times. too much confusing
This is my way, which I like, and some appreciate. Thanks for the feedback!
mr.hindal ghosh ..yea we've understood what have been told in this lecture
if you can't understand you can leave lmao no one's telling you to stay. His explanations are perfect
excellent

Nice ring
I understand the concept, but your teaching speed is so slow that can bore someone, and you're repeating one thing many times which irritated me
no you have lectuer skills
Confusing. .
Aithey chudatam maney
Random variable is a variable. It's not a function. You have to be kidding me. Talk mathematically. Logic doesnt work everywhere.
