Question

Accuracy is ______

(a) ability of the transducer or sensor to see small differences in reading

(b) ability of the transducer or sensor to see small differences in reading

(c) algebraic difference between the indicated value and the true or theoretical value of the measurand

(d) total operating range of the transducer

I had been asked this question during a job interview.

This question is from Classification of Transducers in chapter Physiological Transducers of Biomedical Instrumentation

Answer 1

Correct choice is (c) algebraic difference between the indicated value and the true or theoretical value of the measurand

Explanation: Accuracy describes the algebraic difference between the indicated value and the true or theoretical value of the measurand. Resolution is the ability of the transducer or sensor to see small differences in reading. Precision refers to the degree of repeatability of a measurant.
