Precision of measured values refers to how close the agreement is between repeated measurements. Precision implies the level of variation that lies in the values of several measurements of the same factor. Precision refers to how close two or more measurements are to each other, regardless of whether those measurements are accurate or not.

Precise location data may measure position to a fraction of a unit (meters, feet, inches, etc.). Accuracy is also used as a statistical measure of how well a binary classification test correctly identifies or excludes a condition. When a number of measurements is done to a stable voltage or other parameter, the measured values will show a certain variation. Significant figures (also known as the significant digits, precision or resolution) of a number in positional notation are digits in the number that are reliable and necessary to indicate the quantity of something.
