There are two . contexts precision . and accuracy apply to: sets of data, and measuring instruments.. In a set of data, those measures give an idea of the spread and “. ballpark. ” of the answer (final measurement).. Accuracy of a measurement:. An indication of how close the measurement is to the accepted value. Percentage difference can be calculated to give a quantitative indication of a measurement’s accuracy—the smaller the percentage difference, the greater the . J. Cho.
