Abstract
AbstractDiscussion in this paper centers around the circumstances under which unequal sample size in the two-group study arises and when the point-biserial correlation resulting therefrom should be construed as attenuated and therefore corrected. Formulas are provided for correcting the coefficient either directly or through the mediation of relevant statistics found in studies where the coefficient itself is not reported. Problems and solutions discussed in the two-group study with a single dependent or independent measure are generalized to the two-group study with two or more such measures.
