Web The Point Biserial Correlation Is Used To Measure The Relationship Between A Binary Variable, X, And A Continuous Variable, Y.

Web like all correlation coefficients (e.g. Web the biserial correlation measures the strength of the relationship between a binary and a continuous variable, where the binary variable has an underlying continuous distribution but is measured as binary. In most situations it is not advisable to dichotomize variables artificially. Since the correlation coefficient is positive, this indicates that when the variable x takes on the value “1” that the variable y tends to take on higher values compared to when the variable x takes on the value “0.”
