Which statement correctly describes a characteristic that a scientific measuring tool should have?

A. To be precise, it must be able to make measurements repeatedly

over a long period of time.

B. To be precise, it must be able to make measurements with small

units.

C. To be precise, it must be able to make measurements that are

close to the actual value.

D. To be precise, it must be able to make measurements with both

large and small units.

A. To be precise, it must be able to make measurements repeatedly over a long period of time.

Explanation:

The precision of a scientific measuring tool can be defined as how close the values between multiple measurements are to each other, when repeated under the same conditions.

This ultimately implies that, the precision of a scientific measuring tool reflects the reproducibility and repeatability of its measurements, irrespective of how accurate the measurements are.

In science, one of the most effective ways to determine the precision of a scientific measuring tool is to find the difference between the highest and lowest measurements (measured values).

Hence, the statement which correctly describes a characteristic that a scientific measuring tool should have is that, to be precise, it must be able to make measurements repeatedly over a long period of time.
