    THANK YOU! I hate when professors or books talk like we already know why this normal distribution exist. Very helpful!

  • @sathiswaranpalanisamy4471

    I have been learning statistics as part of AIML, confused so long why and where to calculate z-score and p-values. Your simple and amazing explanations save my lot of time. Thanks a lot!!! Truly you are a legend

    Why Normal Distribution is everywhere
    Answer: Central limit theorem(as n increases, the distribution of the sample mean or sum approaches a normal distribution)
    7:02- Converting Any Normal Distribution to Standard Normal Distribution(Where Mean=0 and Std=1)
    by using z score and the value which is obtained after applying z-score is the value which will fall in the standard normal distribution

  • @justahumann810
    @justahumann810 Před rokem +2

    For those wondering how we use the Z distribution table : We simply do this algebra 0.4998 (for Z being the biggest value in the table which is 3.59) - 0.4332 (Z = 1.5) = 0.0666 ~ 0,067 (I guess so... )

    Very nice visual way of teaching. The software you are using helps to make connection between various parts of learning, when zoomed out. When zoomed out, I get the "I can see the bigger picture" feeling. This software can easily transfer to visualising subjects like history and many more.

  • @hugueslortieforgues3867
    @hugueslortieforgues3867 Před 8 lety +36

    I find the picture of the students in the classroom at 2:02 very misleading! It has the shape of a normal curve, but it is not a normal curve. The taller students should be on the right side, not in the middle.

    • @nirajpatel2400
      @nirajpatel2400 Před 4 lety

      I was also thinking the same...

    • @mouli106
      @mouli106 Před 4 lety +1

      The whole idea is to correlate that as the number of students increase, the arrangement of heights tend to be a normal curve. Thus find the arrangement in line with whats being explained.

    • @krishnabarfiwala5766
      @krishnabarfiwala5766 Před 3 lety

      True but then how would the height variable explain normal distribution??

    I think the probability you found for above 190 cm height should be on the left of the line towards mean and not at the right of 190 cm line.its a mistake. It should be 1-0.067

    1.5 z value = 0.933 , this is area till 1.5 or upto 190 height, we are looking for greater than 190, so the calculation is 1-0.933 = 0.067. Love you all. Peace

    For two coin toss, total outcomes are HH, HT,TH,TT
    0H = TT => 1/4 = 0.25
    1H = HT,TH => 2/4 = 0.50
    2 H = HH, => 1/4 = 0.25

  • @dean8147
    @dean8147 Před 3 lety

    Which distribution theoretically, represents the distribution of arrival rates of an event taking place.? Not sure if this is articulated well enough however i have a dataset that captures the arrival rate of unscheduled cars arrving at a garage for emergency repair. Sampling the data and plotting it on a histogram; it takes form of a normal distribution but im uncertain in my decison. Thanks for anyone who can help.

    At 4:17 the probability of getting six (the shown value) is wrong. Isn't it? I would expect to get 1/6 and not 0.33

    • @gian-lucahardmeier2806
      @gian-lucahardmeier2806 Před 3 lety

      the probability of getting one 6 is actually 0.323. you can calculate this like that: 1. what do we want to calculate? -> the probability of getting one 6 2. how many rolls? -> 10. if you think about it, one possible scenario where we hit only one 6 could be (no = not 6, yes = 6): no, no, no, no, yes, no, no, no, no, no. now you have to calculate the probability of that scenario: (5/6)^9*(1/6) = 0.0323 (5/6)*9 because thats the probability to roll no 6 for 9 times and (1/6) for rolling one 6. but thats only one possible scenario. If you think about it, there are 10 possible scenarios with 10 rolls and only hitting a 6 once. you could roll a 6 with roll number 1 and then 9 times no 6. or you roll a 2, then a 6 and then 8 times something except a 6. so to recap there are 10 different scenarios and on scenario has the probability of 0.0323 which means: 0.0323 * 10 = 0.323
