title: NOTE ON THE EQUIVALENCE OF THE SIGNIFICANCE TEST OF THE PARTIAL POINT-BISERIAL CORRELATION AND THE ONE-FACTOR ANALYSIS OF COVARIANCE FOR TWO TREATMENT GROUPS.
abstract: An identity is demonstrated between (1) the squared Student's t-statistic obtained as a transformation of the sample point-biserial correlation coefficient relating dichotomous variable, 21, to continuous variable x, with the effects of a third variable, x, partialed out; and (2) the F-statistic resulting from a one-factor, two-group (the y dichotomy) analysis of covariance on the x variable Mth the third variable, x, covaried.
