Der Box-Plot (auch Box-Whisker-Plot oder deutsch Kastengrafik) ist ein Diagramm, das zur grafischen Darstellung der Verteilung eines mindestens ordinalskalierten Merkmals verwendet wird. Es fasst dabei verschiedene robuste Streuungs- und Lagemaße in einer Darstellung zusammen. Ein Box-Plot soll schnell einen Eindruck darüber vermitteln, in welchem Bereich die Daten liegen und wie sie sich über diesen Bereich verteilen. Deshalb werden alle Werte der sogenannten Fünf-Punkte-Zusammenfassung, also der Median, die zwei Quartile und die beiden Extremwerte, dargestellt.
