Abstract

In diesem Beitrag werden beispielhaft Probleme der Validität bei Retrievaltests behandelt. Die externe Validität wird im Zusammenhang von Ähnlichkeitsmaßen und Bewertungsmaßen diskutiert. Die interne Validität wird am Beispiel der Mittelwertbildung diskutiert. Es zeigt sich, daß die Forderung nach Validität die zur Auswahl stehenden Methoden einschränkt
