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

    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!

    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 ..

  • @saraman1231
    @saraman1231 3 года назад +4

    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.

      @rahiqueabdul392 5 лет назад

      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

    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.

  • @अण्वायुवरीवर्त

    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 🙏🙏
