Problem 11DQ

Three archers each fire four arrows at a target. Joe’s four arrows hit at points 10 cm above, 10 cm below, 10 cm to the left, and 10 cm to the right of the center of the target. All four of Moe’s arrows hit within 1 cm of a point 20 cm from the center, and Flo’s four arrows hit within 1 cm of the center. The contest judge says that one of the archers is precise but not accurate, another archer is accurate but not precise, and the third archer is both accurate and precise. Which description applies to which archer? Explain.

Step-by-Step Solution:
Step 1 of 3

Solution 11DQ Accuracy means how close a measured/obtained value is to the known or standard value of a physical quantity. Precision means the measurements of a particular physical quantity are all close to each other. Let us now analyse the situations given in the question. Joe: Joe is not precise. Because his hits are not at the same position or close by. They are all at a fixed distance from the center in all directions. Therefore, Joe is accurate, not precise. Moe: Moe is precise. Because his hits are all close to one another. But he is not accurate as all his hits are 20 cm away from the center. Flo: All the four hits of Flo are within 1 cm of the center. This means they are not only close to each other , but also close to the center. So, Flo is both accurate and precise.
