PrecisionPrecision
PrecisionPrecision
Precision is how closely repeated measurements
agree with each other. Precision is usually
expressed as standard deviation (SD).
AccuracyAccuracy
AccuracyAccuracy
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 1.50
mg/L Iron and a representative lot of reagent, an
operator obtained with a single instrument a
standard deviation of 0.010 mg/L.
