ACCURACY AND PRECISION ... Even though physicists usually try for a high degree of precision, there are times when only a close approximation is neeed. Physicists some times make rough estimates for making tentative decisions. The accuracy of estimates depends on reference materials available, time devoted,

Accuracy and Precision ... Accuracy refers to the closeness between measurements (observations) and their expectations ("true" values). The farther a measurement is from its expected value, the less accurate it is. ... Precision pertains to the closeness to one another of a set of repeated observations of a random variable.
