Precision
Precision: (1) Extent to which a given set of measurements of the same sample agree with their mean.
Definition
(1) Extent to which a given set of measurements of the same sample agree with their mean. Thus, precision is commonly taken to be the standard deviation estimated from sets of duplicate measurements made under conditions of repeatability, that is, independent test results obtained with the same method on identical test material, in the same laboratory or test facility, by the same operator using the same equipment within short intervals of time. (2) Degree of refinement in measurement or specification, especially as represented by the number of digits given.
