Precision vs. Accuracy: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Precision is the consistency of results, while accuracy is the closeness of results to a true or target value.
Key Differences
Precision refers to the consistency and repeatability of measurements or results, without necessarily being close to the true value. Accuracy, in contrast, indicates how close a measurement is to the actual or true value.

In precision, multiple measurements yield results that are very close to each other. In accuracy, the measurements, whether consistent or not, are close to a specific target or true value.

A high level of precision in measurements does not guarantee their accuracy. Accurate measurements can sometimes lack precision if they are not consistently repeatable.

To achieve precision, control over the measurement process and consistency is key. To ensure accuracy, calibration against a standard or known value is essential.
