Disambiguation and content mixed on same page.[edit]

This page begins as a disambiguation page, listing links related to "correlation coefficient", but the second half is more like an article (content) about correlation coefficient. Shouldn't the article be separated from the disambiguation page? — Preceding unsigned comment added by 207.194.128.121 (talk) 01:48, 17 June 2015 (UTC)[reply]

Parametric and nonparametric[edit]

This article could go further in clarifying how Pearson's product moment is used for parametric data, Spearman's rank order coefficient is used for nonparametric data. Vorbee (talk) 09:03, 26 December 2017 (UTC)[reply]

That sounds like a job for a subject matter expert. bd2412 T 14:48, 26 December 2017 (UTC)[reply]

Clarification on names (and alternate names) of different types of correlations requested[edit]

Hi, Some people refer to a "bivariate correlation" as their data analysis (e.g. Nelson, Young, Young, & Cox, 2010). It seems to me like bivariate could refer to any of the correlations that only have two variables, though, but the page on bivariate correlation doesn't really enlighten on if it refers to any of the correlational coefficients listed on the correlation coefficient page, or if it is a group name for all correlations that involve two variables, or quite how it fits in with the other correlation coefficients on this page. Adding more to this article (and the bivariate correlation page!) about the terms or alternate terms for correlation coefficients would be helpful.
