the list shows the results of six athletes competing in the long jump, which has a target distance of 20 feet. 12 feet, 11 feet, 13 feet, 10 feet, 20 feet, 12 feet. which best describes the results? fairly accurate but not precise fairly precise but not accurate not precise and not accurate fairly precise and fairly accurate
Accuracy refers to how close a measurement is to the true or target value. Precision refers to how close repeated measurements are to each other. Here, the target is 20 feet. Only one value is 20 feet, so not very accurate. The values 10, 11, 12, 12, 13 are somewhat close to each other but far from 20 overall, so not very precise either.
