FIGURE 18.6. Accuracy and precision.


Accuracy and precision. Accuracy is defined as closeness of a measurement to its true physical value (its veracity), whereas precision is degree of reproducibility or repeatability between measurements, usually measured as standard deviation of distribution. “Target analogy” shows high precision but poor accuracy (left), and good average accuracy but poor precision (right). The archer would correct his or her aim by calibrating sights of the bow. Similarly, perceptual systems can correct for a bias by cross-calibration between senses.
