How repeatable a measurement is.
How repeatable a measurement is. A high precision measurement will be the same, or very similar, every time it is made under unchanged conditions. An imprecise measurement will vary. Precision is not the same as accuracy, which describes how close to the actual value a measurement is. Measurements can be precise but inaccurate, or imprecise but accurate.
