what describes the results of \person three?\

accurate only

accurate and precise

precise only

Explanation:

Accuracy refers to how close a measurement is to the true or accepted value. Precision refers to how close measurements of the same item are to each other. In the dart - board analogy, if the darts are clustered together (showing that repeated measurements are close to each other), it indicates precision. If they are also near the center (the target or 'true' value), they are accurate. In the given dart - board for "Person Three", the darts are clustered together (showing precision) but not near the center (not showing accuracy).

Answer:

precise only
