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

2.00 mg/L cooper and a representative lot of

reagent, an operator obtained with a single

instrument a standard deviation of 0.06 mg/L.
