SPECIFICATIONS
Precision is how closely repeated measurements
agree with each other. Precision is usually expressed
as standard deviation (SD).
Accuracy is defined as the nearness of a test result to
the true value.
Although good precision suggests good accuracy,
precise results can be inaccurate. The figure explains
these definitions.
In a laboratory using a standard solution of 0.750
mg/L Copper and a representative lot of reagent, an
operator obtained with a single instrument a standard
deviation of 0.015 mg/L.
