    Thank you very much for sharing. I'm coming from a computer science background and I needed to understand the usage of the formula in real word and this video is what I was looking for. If you are interested in a real-life use case of the formula you may it's usage is NLP when you want to find the correlation between datasets and words.

    An excellent and poignant example. Well done!
    Price fluctuations don't conform to a normal distribution, as many things. When multiple modes (repetitious data, fractional ranks) occur in significance, this would seem to revert the Spearman back toward the Pearson. The coefficient of 6 in front of sigma almost seems magic for integer ranks.

    • @EugeneOLoughlin
      @EugeneOLoughlin  ปีที่แล้ว

      Hi Aribariho,
      First - many thanks for watching my video!
      Many statisticians say that this test should not be used if some values are the same, as this compromises the test. If you have a lot of similar values, for example - if a lot of the prices are the same, then you should not use this test. Use the Pearson Correlation test instead.
      However, the test can be used if there are a small number of similar values. In my example, let's say that there are two bottles of water at €1.80. These would be the second and third ranks. Simply add 2 + 3 to get 5 and divide by 2. In other words, you get that average for the ranks. 5/2 = 2.5, therefore both would be ranked at 2.5.
      Hope this helps,
      Dr E.

  • @tomworrall190
    @tomworrall190 ปีที่แล้ว

    2 questions:
    (1) Why was the order shortest distance to longest distance and highest to lowest price (10 going to 1)? Presumably because we could see on visual inspection that price decreased with distance. What if this hadn't been obvious?
    (2) Could we maintain the rank order but go the other way around? (In point one above swap 10 and 1). Presumably this wouldn't impact d squared.

    • @EugeneOLoughlin
      @EugeneOLoughlin  3 ปีที่แล้ว

      Hi Leda,
      The Spearman Rank Correlation Coefficient calculation is affected if there are tied ranks. Many statisticians are OK if there are just a small amount of tied ranks in large sample, but it is recommended that you use the Pearson coeeficient if you have tied ranks.
