How To... Calculate Spearman's Rank Correlation Coefficient (By Hand)

Use the Spearman Rank Correlation Coefficient (R) to measure the relationship between two variables where one or both is not normally distributed. This is a non-parametric ranks based test. Note: There are no ties in the data used in this video. If your data has ties you should consider using a different test (eg Kendall's tau). Made with GoPro.

[@lowellhanson5800]

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.

[@NavidKalaei]

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.

[@tomworrall190]

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.

When Ranking the data figures, make sure that the ranks are in ASCENDING ORDER. The rank of 1 being assigned to the smallest figure while the rank of 10 being assigned to the highest figure. Make sure to do so.

[@aribarihodenzelowens9118]

Thanks so much. But then what do you do in cases where the x variables are similar. Do you rank them the same??

[@EugeneOLoughlin]

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.
