Accuracy refers to how close the measured values are to the true or target value. In this case, the true value would be 500 g. The scale's measurements of 397 g, 401 g, and 403 g indicate that it consistently measures a value lower than the true value. Therefore, the scale is not accurate.
Precision, on the other hand, refers to how consistent the measurements are regardless of whether they are close to the true value. The measurements of 397 g, 401 g, and 403 g are relatively close to each other, with a range of only 6 g. This suggests that the scale is precise, as it consistently produces similar measurements.
In summary, the scale is precise but not accurate.
A set of 500- G masses is placed at a time on a digital balance during control testing. The mass readings are 397 g, 401 g, and 403 g. Describe the accuracy and precision of the scale
