    This is literally the best video I've came across that let me intuitively understand not only Normal Distributions, but especially PDFs and CDFs, along with PPFs that I didn't know about.

    Man this is real gold. I already know what normal distribution and all are, I just casually clicked your video and was engaged till the end. This is some serious editing and animation of those graphs right there. Subscribed.

    This is beautifully done! I can imagine a time (not long from now) when these presentations can be made interactive with an AI that can alter these graphics and explanations to respond to student questions. That will be quite an exciting time for education.

      The Z-scores are the x-axis but only after the standard deviation has been scaled to 1, and the mean has been scaled to 0. If I have time I'll make a video about this.

    at 2:30....why is looking at likelihood NOT meaningful in itself ?

    • @3-minutedatascience
      @3-minutedatascience  5 місяців тому

      I will make a video about this later, but the probability of getting EXACTLY 61.53 pounds... is 0%. In continuous variables, decimals can have an infinite number of decimal places, driving any specific value to have a probability of 0. You have to look up ranges of areas to get probabilities instead.

    I know that you write books about statistics, but you made a mistake in the formula of the normal distribution. In the first term the sigma must be as sigma squared within the square root. This is is important, because if you put sigma infront of the root and sigma is negative, then also the likelihood in of your PDF will become negative which makes no sense. I made this mistake myself once and it caused my some trouble in my calculations, hence I know this pain very well...
