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.
For each parameter, the precision is expressed in the related measurement
section as standard deviation at a specific concentration value of the
analite. The standard deviation is obtained with a single instrument using
a representative lot of reagent.
