Question

If a student’s measurements are precise but not accurate, it means:
Options
A Values are close to true value
B Values are inconsistent
C Values are close to each other but far from true value
Correct Answer
D Measurements were not taken properly
Correct Answer

Option C is the correct answer.

Detailed Explanation

Precision refers to the agreement between repeated measurements. Accuracy refers to agreement with the true value. Precise but inaccurate measurements are tightly clustered together, but that cluster is centered away from the true value.

Hint

Imagine a tight group of shots that are all in the same spot, but that spot is not the bullseye.
