preciseaccurate

Preciseaccurate is a coinage used in some technical, educational, and branding contexts to describe a measurement or result that is both precise and accurate. It is not an established metrological standard, but it is sometimes employed to emphasize the combination of repeatability and correctness.

In metrology, precision refers to the closeness of agreement among repeated measurements (low random error), while accuracy refers to how close a measurement is to the true value. A measurement can be precise but not accurate (repeatable results that are far from the true value), accurate but not precise (close to the true value on average but with high variability), or both precise and accurate (consistent results near the true value with little dispersion).

In practice, reporting a single figure can be misleading. The idea behind preciseaccurate is most effectively conveyed by presenting both the estimate and its uncertainty, and by describing the calibration status of instruments. In quality control and laboratories, calibration records and traceability to standard references are used to support claims of precision and accuracy.

Status and usage: The term preciseaccurate is relatively rare in formal standards. For formal documentation and standards-compliant reporting, it is better to separately discuss precision and accuracy or to quantify measurement uncertainty. When encountered, the term should be defined clearly within the context of the document to avoid ambiguity.
