c. reproducibility

b. accuracy

d. usefulness 14. which group of measurements is the most precise

The closeness of a measurement to its true value is a measure of its accuracy.

Explanation:

Precision refers to the closeness of two or more measurements to each other. Example: If we measure weight four times and we get 60 kg each time. Then the measurement is very precise.

Accuracy refers to the closeness of a measured value to a standard or known value. Example: If the weight of the body is 60 kg and one person measures 58 kg and another person measures 59 kg. Then, the weight measured by second person is more accurate.

Thus the closeness of a measurement to its true value is a measure of its accuracy
