Which of the following conditions does repeatability in measurement involve?

Repeatability in measurement refers specifically to the precision of measurements taken under the same conditions. It involves performing the same measurement procedure multiple times, ideally with the same operator and equipment, to ensure consistent results. This means that when a measurement is repeated, it should yield results that are closely aligned if the same methodology is applied.

By focusing on the same measurement procedure, the influence of other variables such as operator variability, environmental factors, and instrument differences is minimized, allowing for a clearer assessment of the capability and reliability of the measurement system. This is a key principle in fields that require rigorous data collection and analysis, ensuring that the results are stable and replicable.
