Final answer:
A device that delivers highly repeatable results has good precision, which indicates consistency in measurement but does not guarantee that the measurements are accurate or close to the true value.
Step-by-step explanation:
A measuring device that produces highly repeatable results is said to have good precision. Precision refers to the consistency of repeated measurements, where results that are similar to one another suggest a high degree of precision. This is independent of accuracy, which means how close a measurement is to the true or accepted value.
In contexts such as an archery competition, if all arrows land closely together but away from the bulls-eye, this would represent good precision but potentially poor accuracy.
In contrast, if the arrows are scattered but center around the bulls-eye, the shooter has good accuracy with poor precision. It is the goal in scientific measurements, as well as other precision-dependent tasks, to achieve both good accuracy and good precision to ensure the most reliable and valid results.
