Reference: AQA
Unpredictable variations in repeated measurements about a mean value, caused by factors such as fluctuating temperature, vibration or inconsistent reading of a scale.
Errors that vary unpredictably between readings, often due to fluctuations or reading uncertainty, and affect precision.
