    Would you like to run some statistics? Or observe phenomenon and render hypophysis of said phenomenon?

    One thing I appreciate is how this starts off using simple language to explain the concept, and then immediately derails into nonsensical terms like "P hat" and "Z star". The inability to explain something in simple terms without using nonsense jargon is the benchmark for gatekeeping and elitist thinking. It seems this professor would rather be stuck in his masturbatory ivory tower instead of teach his seemingly arcane topics to the common man.

      it's not that deep... most people watching this already know these terms anyway. There is no "common man" trying to learn this level of stat out of nowhere.

      @@magicativ4809 Careful you don't hurt your arm trying to jack yourself off so intensely. The video is titled "Introduction to Statistics".
      There are honest videos that actually intend to "introduce" people to a category of learning, and then there is this kind of video that can't go five seconds in without using seemingly profound mumbo jumbo.

      @@master_branch It says introduction to t statistics. Not intro to stats. These values are already explained in other videos and there is an expectation that the viewer already knows these values from z statistics before moving on to t stats.

    What if I want to compare two groups that are not the same thing, using the t-value? I am making a survey. I want to see the relationship between the number of trips attracted by a building and compare with it's constructed area. I have one sample of 5 elements of each parameter.

    from where do you get the sqrt of n? Why was it sigma_statistics and then turned to be sigma/sqrt(n) ?

    • @sixtysixx3933
      @sixtysixx3933 5 ปีที่แล้ว +1

      After researching for few hours, I found that the point of sigma/sqrt(n) is what they call the standard error which is basically the standard deviation of the means. And this formula will be sigma^2 / n. Rewrite it you will get that sigma/sqrt(n). The concept behind this is basically assuming that if the sample size n is huge enough the closer you will get to the real population mean.
