Accuracy and Precision

Accuracy- indicates the difference between measured value and the expected (true) value. If observed (measured) values are near the expected (true) value, the measurement has high accuracy. Precision- indicates the differences among each measured value; if measured values are close together the measurement has high precision.

Error and Deviation Error expresses accuracy in the form of a number that relates the measured value to the true (expected) value. Deviation expresses precision in the form of a number that relates the measured value to its closeness to other measured values.
