When the variance of either variable in a correlational analysis is inflated by the sampling procedure, the resulting correlation coefficient tends to be higher. This is because correlation coefficients measure the strength and direction of a linear relationship between two variables, and an increase in the variance of one or both variables can artificially inflate the perceived strength of this relationship.
