Question

A student measures the length of a quarter-mile lap around the school's track to be 402.3 meters, 402.3 meters, and 402.5 meters. If the accepted value for the path is 402.3 meters, the student measurements are...

1. Precise only

2. Accurate only

3. Both precise and accurate

4. Neither precise nor accurate.

Answer 1

Both precise and accurate

Step-by-step explanation:

If the average of the measurements is close to the accepted value, these are accurated. While precision refers to how close the measurements are between them. In this case the measurements are close to each other, therefore, these are precise. The measurements are also close to the accepted value, therefore, these are accurate.
