- Summary:
-
Besides the ubiquitous Pearson product-moment r, there are a number of other measures of relationship that are attenuated by errors of measurement and for which the relationship between true measures can be estimated. Among these are the correlation ratio (eta squared), Kelley's unbiased correlation ratio (epsilon squared), Hays' omega squared, and the intraclass coefficient of correlation, expressed as a ratio of variance components by Ronald Fisher. This paper shows how to correct each of these for attenuation. Such corrections permit estimates of relationships between true scores to be made when estimates of relevant reliability coefficients are available. (Author)
