Which term means how close the value is to the true value ( bulls-eye )?

• A. Precision
• B. Imprecision
• C. Inaccuracy
• D. Accuracy

Answer: (D)

Closeness to the true value is accuracy. The bull's-eye represents the true value, so measurements that land near it are accurate. Precision, by contrast, is about how repeatable or tightly clustered the measurements are, not how close they are to the true value. You can be precise but not accurate if your results cluster away from the true value, or accurate but not precise if your results average near the truth but vary widely. So the term that means closeness to the true value is accuracy.
