## How To Find Accuracy And Precision

The term precision should not be used for accuracy [1]. 9. Trueness designates closeness of agreement between the average value obtained from a large series of test result and an accepted reference value [3]. Notes The measure of trueness is usually expressed in terms of bias [3]. Trueness has been referred to as “accuracy of the mean”, what is not recommended [3]. 10. Precision …

- What Is Accuracy? While the words "accuracy" and "precision" have pretty much the same meaning in everyday life, they mean quite different things in the world of numbers and measurements.
- The coefficient of variation (CV) is defined as the ratio of the standard deviation to the mean: It shows the extent of variability in relation to mean of the population.
