Measurement

Systematischer Fehler

Definition

Eine konsistente, reproduzierbare Abweichung von Messwerten vom wahren Wert, verursacht durch einen Mangel im Instrument, in der Methode oder im Versuchsaufbau.

Erklärung

A scale with a 0.5 g offset reads every measurement as 0.5 g too high — this is a systematic error that averaging many measurements cannot eliminate. A thermometer not accounting for stem correction will always read slightly too low. Unlike random errors, systematic errors shift all readings in the same direction and require identifying and correcting the root cause.
