Accuracy versus Precision?

YES – There is a Difference

[By staff reporters]

ACCURACY Defined

The degree to which a measurement, or an estimate based on measurements, represents the true value of the attribute being measured. In the laboratory, accuracy of a test is determined when possible by comparing results from the test in question with results generated using reference standards or an established reference method.

PRECISION Defined

Precision is a description of random errors, a measure of statistical variability. It refers to the closeness of two or more measurements to each other.

ACCUAACY versus PRECISION

Both accuracy and precision reflect how close a measurement is to an actual value, but accuracy reflects how close a measurement is to a known or accepted value, while precision reflects how reproducible measurements are, even if they are far from the accepted value.
