Question

Nancy measured the volume of the liquid in her experiment five times (95.0 mL, 95.5 mL, 90.5 mL, 97.0 mL, 96.5 mL). The exact measurement is 96.1 mL. What can be concluded about the precision and accuracy of her measurements?

Answer 1

It can be concluded that there is very little precision and accuracy as she was over 5mL off at one point.

Answer 2

Answer:

The measurement is not at all accurate and precise

Explanation:

Precision of any measurement is its nearness to the actual value. Here, all the measurements $95.0, 95.5, 90.5, 97.0, 96.5$ have a significant difference in reference to the exact value i.e $96.1$. Thus, all these measurements are not precise.

The accuracy of any measurement is its exactness to the actual value. Here, none of the values lie near to the exact measurement i.e $96.1$. Thus, all the measurements are not accurate even.
