In much research in social psychology it is impractical to get quantitative measure of the degree of effectiveness of certain social behaviors, yet associates can sense that effectiveness sufficiently well to detect those who manifest the behavior in very high or in very low degree. This paper develops a technique of biserial correlation from wide-spread classes to deal statistically with such situations, develops standard error formulas for it, and points to a wide range of usefulness for this type of technique.
