What is the difference between accuracy and precision in the context of medical device calibration?

Accuracy and precision are two distinct concepts in the context of medical device calibration, each describing different aspects of measurement quality. Accuracy refers to how close a measurement is to the true or accepted value. A device is considered accurate if its readings consistently reflect the actual quantity being measured. For instance, if a blood pressure monitor consistently displays a blood pressure reading that is very close to the patient's actual blood pressure as determined by a calibr....
