TERMINOLOGY — symmetric accuracy range, relative (%) range of 95% of a method’s measurements about the (true) measurand — 95% confidence limit on the symmetric accuracy range — mean concentration estimate bias relative to the (true) measurand — bias estimate — concentration estimate — true concentration — reference concentration (estimate) — coverage factor, a constant containing confidence information for obtaining the expanded uncertainty as a factor of the combined uncertainty — detection limit (for controlling false negatives) — limit of detection (for controlling false positives) — number of measurements in a method evaluation — unbiased estimate of variance — jth population variance component — (true) relative standard deviation — (true) relative standard deviation in reference concentration (estimates) — jth uncertainty component, an estimated standard deviation — combined uncertainty, pooled uncertainty components — expanded uncertainty, a value giving intervals bracketing the (true) measurand at given confidence in the measurement and method evaluation
