    5.3. PRECISION & ACCURACY Precision is how closely repeated measurements are to one another. Precision is usually expressed as standard deviation (SD). Accuracy is defined as the closeness of a test result to the true value and is method specific. Although good precision suggests good accuracy, precise results can be inaccurate.
