3. Accuracy and Precision

4. 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.

5. 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.
