How is accuracy and precision measured in engineering?

Precision: take several samples and do a statistical variation. If the average between the differentiation is close to 0, the system is precise. Accuracy: take several samples and compare them to a target threshold, the closer the average distance to the threshold, the more accurate it is. read more

In addition to accuracy and precision, measurements may also have a measurement resolution, which is the smallest change in the underlying physical quantity that produces a response in the measurement. read more

In other words, the precision of an experiment, object, or value is a measure of the reliability and consistency. The accuracy of an experiment, object, or value is a measurement of how closely results agree with the true or accepted value. Both accuracy and precision are terms used in the fields of science, engineering, and statistics. read more
