systematic error
Quick Summary
In science, systematic error refers to inaccuracies in observation or measurement that are inherent to the system itself, rather than being due to random chance. These errors are predictable and can often be identified and corrected.12
For example, an improperly calibrated instrument can introduce systematic error. Unlike random errors, which cause small fluctuations that can be minimized but not eliminated, systematic errors consistently skew results in a particular direction. Evaluating results in scientific analysis involves understanding both accuracy (agreement with the true value) and precision (reproducibility of measurements), with systematic errors impacting accuracy.2
