Detailed explanation-1: -Precision refers to how close measurements of the same item are to each other. Precision is independent of accuracy. That means it is possible to be very precise but not very accurate, and it is also possible to be accurate without being precise. The best quality scientific observations are both accurate and precise.
Detailed explanation-2: -The closeness of two or more measurements to each other is known as the precision of a substance. If you weigh a given substance five times and get 3.2 kg each time, then your measurement is very precise but not necessarily accurate. Precision is independent of accuracy.
Detailed explanation-3: -Accuracy is the closeness of the measured values with the standard value whereas, precision is the agreement of the measured values among themselves. The correct answer is (D).
Detailed explanation-4: -Summary. Accuracy and precision are both ways to measure results. Accuracy measures how close results are to the true or known value. Precision, on the other hand, measures how close results are to one another.
