precision

 [pre-sizh´un]
1. the quality of being sharply or exactly defined.
2. in statistics, the extent to which a measurement procedure gives the same results each time it is repeated under identical conditions.

pre·ci·sion

(prē-si'zhŭn), Do not confuse this word with accuracy.
1. The quality of being sharply defined or stated; one measure of precision is the number of distinguishable alternatives to a measurement.
2. In statistics, the inverse of the variance of a measurement or estimate.
3. Reproducibility of a quantifiable result; an indication of the random error.

precision

Lab medicine A measure of test or assay reproducibility–ie, capability of producing the same results when performed on the same specimen under the same conditions; data with high precision has a low standard deviation and a low coefficient of variation. Cf Accuracy.

precision

the quality of being sharply defined by virtue of exact detail, an important criteria of a diagnostic test. A precise test is free from random error. Precision is a requirement of accuracy.
