precision
[noun]
In science, precision refers to the degree of specified detail which can be expressed in a value. For example, a value expressed to three decimal places can be considered more precise than one made to two places. The determination of precision is a function of the degree to which individual measurements vary around a central value. Values with high precision are highly reproducible because repeated measurement will reliably give a similar result; however, they may or may not be accurate. Precision relates to the statistical error associated with a value. Compare to accuracy. See the module Uncertainty, Error, and Confidence.
