    You are a one stop shop for bio, chem and math. I went from not knowing order of operations to multiplying and dividing rational expressions in 4 months NOT thanks to professors or the math learning center but TO YOU. THANK YOU for everything you do for all of us. YOU are the only one that makes sense to me🤓

    My statistics professor SUCKS! Literally paying thousands to be assigned a chapter with no other instruction, then take a mpc test following. I could have just bought the book and read it. Sadly, this seems to be the trend as this is the 3rd class I've had following this disgusting recipe. So, a huge thank you for this video. YOU deserve the "professor's" fee for actually teaching concepts and making them accessible and understandable. You've made my day.

  • @yaweli2968

    It’s true that the CDF for the uniform is
    (x-a)/(b-a) but if the entire area is not up to one, for instance, if b is the 70th percentile instead of the 100th, this implies the entire area adds up to 70 percent. The CDF changes. It’s the everything like before multiplied by 0.7. Props to this Professor, he is amazing for all courses, what else can this man not teach!

  • @oguzgonul2584

    I took this lesson from a fake teacher called Masood. He just opens the pdf he found from internet and reads it and he dont even know what that means.
    And asking the questions probably he cant answer at midterm and finals.
    After understanding the problem i can finally be happy. Thanks to you

    The Area of line technically referes to an infintesimally area under the curve being a trapizium out the whole distribution equal to one.You can use the leibenz calculus theorem for that.

    Where did the lambda go in 5:33 ? Why do we calculate 1 - e^-lambda * x? Shouldn't it be 1 - lambda*e^lambda*x, since that is our f(x)? Thank you :)

    • @alexssandredeoliveiraj2773
      @alexssandredeoliveiraj2773 4 года назад +3

      To evaluate the area under the curve to the left of some value "x", you have to calculate the integral of f(x) between 0 and x. Doing this the lambda will vanish.

    Very good video. However you should have shown why the cdf for an exponential distribution is 1-exp(-lx) instead of putting the formular. I encourage students to avoid memorization. This can be shown through an integral and you know it but you didn't do it.
