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.

In a summary of Duke's comments on teaching to attendees at the National Conference on Piano Pedagogy in 1990, Joyce Cameron describes Duke's belief that many music teachers allow a very short stage of romance followed by a very long stage of precision and then move on to a brief stage of generalization.
The performer here displays the results of the stage of precision that may have developed earlier in the year and now is performing with newly added depth and maturity.
Also, test precision data must be based on long-term repeatability conditions, and the resulting test immanent data variation can be considered as noise.
test precision is so poor (as compared to the observed variation in product quality) that these tests can only be used to look for outliers, if they should ever occur.
It is very important to note that improving test precision by repeated testing and averaging is not possible with QA testing since sitr could only be improved by repeated testing over periods of weeks or even months which is not practical at all.
and calculated Cp-values are influenced by poor test precision, via equation 3, to only less than 6.1%.
