Talk:Spearman's rank correlation coefficient

Does it anywhere in this article say that p is always a number between 1 and -1, and what high and low values mean?
This page was formerly at "Spearman's ρ" -- however, this breaks "move page" and is against the general naming principle that names should be the most common name, in English, where available. User:The Anome
- Well, this may not be the most common name in English, but the change makes sense because it facilitates linking, especially now that the main alternative titles have redirect pages. I'll remember that next time. Thanks. User:Jfitzg
- Would Spearman's rank correlation coefficient be nicer? -- Oliver P. 16:37 28 May 2003 (UTC)
- That might definitely be better. Perhaps the main article should be there. John F.
- So I moved it. Should have all the bases covered now. John F.
From the article:
- The value of ρ is equivalent to the Pearson product-moment correlation coefficient for the correlation between the ranked data.
Is this an identity or an approximation? If so, it it by definition, by co-incidence, or just for some particular family of distributions?
- Thanks. I'll clarify this. It's a special case of the Pearson.
