Absolute accuracy is generally how it compares to repeatability?

Absolute accuracy refers to how close a measurement is to the true value, while repeatability is the degree to which the same measurement can be replicated under unchanged conditions. Generally, absolute accuracy is considered to be significantly poorer than repeatability because even if a measurement process can consistently yield the same result (high repeatability), that result may still be far from the true value, undermining its absolute accuracy.

In practical terms, this implies that instruments or systems demonstrating high repeatability can produce measurements that are reliable within a specific context but may not be accurate when compared to an established standard or the true value. Therefore, when evaluating tools or processes, it's essential to recognize that high repeatability does not guarantee high absolute accuracy, leading to the conclusion that absolute accuracy is generally significantly poorer than repeatability.
