Accuracy and Precision

Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is ver...

Scientists make repeated measurements of a quantity during experimentation to ensure that their results are accurate and precise.

The accuracy of a measurement is the degree of closeness of the results to the true or accepted value.

Consider two students, A and B, who repeatedly weighed a gold bar known to have a true mass of 10 gr...
