Repeatbare

Repeatbare is a term used in certain technical and scientific communities to describe the property of a process, measurement, or experiment that yields identical results when repeated under the same conditions. It emphasizes stability of outcomes within a single setup and assumes that the instrumentation and procedures are kept constant across trials.

Definition and scope: A repeatbare result means that repeated trials produce results that agree within the stated measurement uncertainty. The concept is intended to distinguish true determinism in an apparatus from outcomes that only appear stable due to varying conditions or observer effects.

Relation to related concepts: Repeatbare is closely related to repeatability in measurement theory, but some writers treat it as a broader or differently focused term. It is distinct from reproducibility, which concerns obtaining the same results across different laboratories, operators, or environments. In practice, the use of repeatbare varies by field, and some communities reserve the term for tightly controlled experiments where environmental factors are deliberately minimized.

Applications: In laboratory calibration, instrumentation testing, and quality control, a repeatbare procedure would be one in which repeated measurements under a fixed setup fall within the measurement uncertainty and show no systematic drift between trials.
