- noun the fact that something is very accurate
- A measure of the repeatability of a given result or procedure, such as a measurement. For example, a measurement made several times in which the same, or nearly the same value is obtained, indicates precise measurement. This does not necessarily mean that such measurements specify or approximate a real value, thus a precise measurement may not be accurate. still, even in technical usage the term is often used synonymously with accuracy.
- The number of significant digits provided in a measurement or other value. The more significant digits, the more precise.
- Pertaining to components, devices, equipment, and systems which are characterized by exactness, such as those which adhere closely to a given standard.
(written as Precision)Precision is a measure of how close an estimate is to the true value of a parameter. Less precision is usually indicated by a larger standard error.
