Technical Note—The Effect of Grouping Continuous Variables on Correlation Coefficients

The purpose of this note is to supplement some recent articles which discuss correlations between two grouped random variables. In this paper we give a more parsimonious and less computationally complex method of assessing the effect of grouping while also giving some insights into the best ways to group continuous variables. Implications of these results for certain marketing studies are given.
