Chapter 18.3: How to Calculate Spearman’s Rank Correlation

In this video, I show you how to calculate Spearman's rank correlation value and also explain what the value means. Note that the value of correlation is always between 1 and 0, and the null hypothesis is always "there is no correlation between two data sets"

If we get a value between 0.5-0.6 so what does that mean will we have to accept the null hypothesis or reject it?

Im sorry but if D is sum of all ranks
According to formula should'nt we square it ?

when u minus 5.5 from 3, its -2.5. the square of -2.5 is -6.25, so why do u write it as positive 6.25?
