Options
A accurate but not precise
B precise but not accurate
Correct Answer
C both accurate and precise
D neither accurate nor precise
Correct Answer

Option B is the correct answer.

Precision refers to the reproducibility of measurements (how close they are to each other). Accuracy refers to how close a measurement is to the true value. If they are close to each other but far from the true value, they are precise but not accurate.

Hint

Think of a dartboard: all darts close together but off-center.
