[This article is] poorly explained. --Eequor 03:39, 22 Aug 2004 (UTC)
This article is incomprehensible to anyone unfamiliar with advanced statistical notation. It could be repaired with a concrete example and an intuitive, rather than symbolic or mathematical explanation. A graph or two would also help a lot. -- Beland 01:54, 23 August 2005 (UTC)
Please include more information
It is worth noting that if the relationship between values of and values of is linear (which is certainly true when there are only two possibilities for x) this will give the same result as the square of the correlation coefficient, otherwise the correlation ratio will be larger in magnitude. It can therefore be used for judging non-linear relationships.
If you understand this thoroughly, please help improving this article and put it more clearly. I am very unhappy with this sentence, since I am not understanding it. I do not want to remove it, since there needs to be a reference made to the correlation coefficient and it seems that the original author knew about it. It would just be nice to convey this message comprehensively. Tomeasy ( talk) 11:32, 29 March 2008 (UTC)
I have taken the later of the two following statements out, since I think it is wrong.
which might be written as
The use of the sigma's implies that we should be dealing with standard deviations here. However, substituting their definition does not yield the given equation. Also it is not very clear to me, what standard deviation is precisely meant in the numerator. I tried interpreting it as the standard deviation of the category means, but it failed to yield the stated equation. Correct me, if I am wrong. Tomeasy ( talk) 11:41, 29 March 2008 (UTC)
I have proposed that this article be merged into intraclass correlation coefficient. The correlation ratio statistic and its population analogue are the same as the ICC (more specifically, the statistic is one of several ICC's in use, and the population value is identical). This particular use of the ICC is different from the usual uses of the ICC, so I would propose adding a new section to the ICC page explaining how the ICC can be used to identify non-linear relationships when data are observed with replication, and stating that the term "correlation ratio" is sometimes used when the ICC is applied in this way.

I've tried unsuccessfully to add a link to the same page in Spanish. Could someone do it? thanks — Preceding unsigned comment added by 190.193.138.41 ( talk) 00:09, 28 May 2013 (UTC)
