- Spearman's rank correlation coefficient.

Find the problem and solution here; I am refreshing on this topic of Correlation.

The steps are pretty much clear..my question is on the given formula ##\textbf{R}##. Is it a generally and widely accepted formula or is it some form of improvised formula approach for repeated entries/data? How did they arrive at... ##m^3-m?## ... Any proofs? Supposing ##9## entries are repeated and ##1## entry is different would the formula still hold?

Are there other different ways of solving this particular problem?

Cheers...
