It is often considerably easier to obtain the value of the point biserial correlation coefficient for a given set of data than it is to obtain the biserial correlation coefficient. A table is presented that directly converts any known point biserial coefficient to the biserial coefficient providing the largest proportion of the dichotomous variable is also known. [ABSTRACT FROM PUBLISHER]

Tables are presented giving the critical values of the Biserial and the Point Biserial correlation coefficients (when the null hypothesis assumes a value of zero for the coefficient) at the 0.05 and the 0.01 levels of significance. [ABSTRACT FROM PUBLISHER]
