Pearson V. Fisher
The correlation ratio was introduced by Karl Pearson as part of analysis of variance. Ronald Fisher commented:
As a descriptive statistic the utility of the correlation ratio is extremely limited. It will be noticed that the number of degrees of freedom in the numerator of depends on the number of the arrays
to which Egon Pearson (Karl's son) responded by saying
Again, a long-established method such as the use of the correlation ratio is passed over in a few words without adequate description, which is perhaps hardly fair to the student who is given no opportunity of judging its scope for himself.
