PRECISION AND ACCURACY
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
1.00 mg/L phosphate and a representative lot of
reagent, an operator obtained with a single
instrument a standard deviation of 0.03 mg/L.
