Auf die Untersuchung des ``rank correlation coefficient'' \[ r'=1-\frac{6 \sum d^2}{n(n^2-1)}, \] wo \(d\) die Differenz im Range eines Individuums, das in zwei Klassen eingeordnet ist, bedeutet, folgt die Ableitung der Verteilung von \(r'\) für kleine Werte \(n\) der Gesamtheit. Die mittlere Abweichung \(\dfrac{1}{\sqrt{n-1}}\) wird bestimmt, ebenso das vierte Moment. Es wird gezeigt, daß die Grenzverteilung von \(r'\) normal ist.
