    I'm falling in love with this series. I have learnt a lot more than what I learnt in school time. Thanks Derek

      That is fantastic to hear! When I decided to finally cover everything needed for data science and ML I figured I'd lose 10 to 20,000 subscribers and nobody would watch the videos. I never considered that it would make my 3,000 great fans very happy, which is good enough for me :)

    Error at @6:52? As N increases, the denominator increases, but so does the number of samples in the summation. Bigger N would be more accurate stdev, not smaller stdev?

      Sorry if I made an error. I'll check and make a correction in the code.

      @@derekbanas No worries, thanks for this great series. I've seen some creators overlay *text on the video to make corrections. Not sure if that's built into the UA-cam UI or if you have to re-render and re-upload.

    Are there any pre-requisites to go through your videos from Probability video to this video ?

      Thank you very much :) No you don't even need to watch the probability tutorial to watch this, but since probability and statistics are normally taught together to get complete knowledge it is best to watch both.

    Hi Derek, good content, but unfortunately there are 2 errors:
    1. The Rocket's salary does not follow normal distribution. Instead, income typically follow Pareto distribution, so no confidence interval interpretation.
    2. CI score calculation is incorrect. x = mean + z * sd (not sd / sd**0.5)

    So when you pass a list of args in, why to you pass it with an asterisk sometimes but not all the time. Should the results be different? I will try when I get back to a computer. Thx
    e.g.
    def add(*args):
    Return sum2 = sum(*args)
    //without
    def add(*args):
    Return sum2 = sum(args)

    • @karenhausman9824
      @karenhausman9824 4 роки тому

      The asterisk means that you can pass any number of arguments in. The results should be the same. Look up "*args, **kwargs"

    Dear mr. Banes why You get rid off f when you format numbers. It's so much easier to write f"{variable:.3f}"

    Hellow you well done Brother ,Do you know how does it works in stock market if you know please replay Thanks

    • @derekbanas
      @derekbanas  4 роки тому

      Thank you :) You basically look for relationships between stock fundamentals, things like stock price, earnings, etc and other factors such as other stock prices, economic indicators, fluctuations in other market values. Then you use things like regression analysis and correlation coefficient to make predictions. I covered both in my statistics learn in 1 video and will cover them in this tutorial next week.
