The correlation ratio is a measure of dispersion with categories relative to the dispersion across the entire dataset. The correlation ratio is a weighted variance of the category means over the variance of all samples.
In statistics, Cramér's V (sometimes referred to as Cramér's phi and denoted as φc) is a measure of association between two nominal variables, giving a value between 0 and +1 (inclusive). It is based on Pearson's chi-squared statistic and was published by Harald Cramér in 1946.
