    Gegeben seien zwei normal bivariate Populationen, in denen der Korrelationskoeffizient unbekannt ist. Aus beiden Bevölkerungen mögen Stichproben vorliegen. Verf. stellt sich die Aufgabe, aus den Stichproben die Wahrscheinlichkeit der Hypothese zu berechnen, daß\ der Korrelationskoeffizient in beiden Populationen der gleiche ist. Er befolgt hierbei das von \textit{Pearson} und \textit{Neyman} für sogenannte zusammengesetzte Hypothesen angebahnte Verfahren. Verf. gelangt zu einer Lösung, die im Falle von Stichproben gleichen Umfangs genau und sonst angenähert gilt.
