    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

    Amazingly explained. I was always confused by Z. You explained why we need to find and use Z. Thanks

  • @justahumann810
    @justahumann810 Рік тому +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... )

    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

    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.

    @3:25
    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

    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

    • @mouli106
      @mouli106 4 роки тому +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

    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

  • @JaiShriRamJaiRaghuveer
    @JaiShriRamJaiRaghuveer 10 місяців тому

    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

    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.

    How is it different from Binomial distribution? Every trial has 2 outcomes, getting a six and not getting a six. Every roll is independent.

    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 4 роки тому

      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
