What is the relationship between precision and repeatability in measurements?

The correct choice indicates that precision is a form of repeatability, highlighting an important concept in measurement theory. Precision refers to the degree to which repeated measurements under unchanged conditions show the same results. It assesses the consistency or reproducibility of measurements.

Repeatability specifically concerns the ability to obtain the same measurement results when the same device is measured multiple times under the same conditions. Thus, if a measurement is precise, it inherently reflects good repeatability, as the measurements would cluster closely together.

In contrast, other choices do not correctly convey the relationship between these metrics. While precision focuses on the closeness of multiple measurements, accuracy deals with the closeness of a measurement to the true value, which is separate from both precision and repeatability.
