Die Abhandlung gilt dem Signifikanzproblem bei Korrelationsuntersuchungen. -- Es seien \(s\), \(S\) zwei unabhängige Stichproben, die derselben normalen zweidimensionalen Verteilung entnommen sind, und \[ v=\frac{1}{n-1} \sum (x_i- \overline{x}) \,(y_i- \overline{y}), \quad V=\frac{1}{N-1} \sum (x_j- \overline{x}) \,(y_j- \overline{y}) \] die zugehörigen empirischen Produktmomente. Verf. berechnet die Verteilungsfunktion des Quotienten \(\dfrac{v}{V}\) und benutzt in einem ausführlichen Beispiel die gewonnene Formel zur Beurteilung der Signifikanz einer Abweichung zwischen zwei Korrelationsbestimmungen.
