Attention is focused on the presentation of circular statistics with directional data, since biologists and physicians are often confronted with such statistical problems. The methodological properties of circular statistics are elaborated by means of data of arterial blood gas changes during exercise in children with cystic fibrosis. The present study demonstrates that performance and discrimination into different severity groups in this chronical disease can be achieved by this statistical method and that analogous problems in biology and medicine could be resolved in the same way.

Die Arbeit will die in ihrer Anwendung nicht oft durchgeführte Methode der Kreisstatistik zur Auswertimg bidirektioneller Daten vorstellen. An Hand der Daten von arteriellen Blutgasanalysen, die bei Kindern mit zystischer Fibrose (Mukoviszidose) während eines Arbeitsversuchs gewonnen worden sind, wird die statistische Verarbeitung dargelegt. Die Resultate zeigen, daß sowohl eine Aussage bezüglich der körperlichen Belastbarkeit als auch eine Unterscheidung und Zuordnung dieser Kinder in Gruppen verschiedenen Schweregrades möglich ist. Diese Methode würde sich auch bei anderen analogen statistischen Problemen der Biologie und Medizin anwenden lassen.
