Student measures the mass of a paper clip. the students data table is shown below. the acceptable value for the paper clips is 1.14g.
trial # mass
1 2.45 g
2 2.40 g
3 2.42 g
which of the following best describes the students measurements
the students measurements were accurate, but not precise
the students measurements were precise, but not accurate
the measurements are neither accurate nor precise
the measurements are both accurate and precise

Option , B, the students measurements were precise, but not accurate

Explanation:

It is given that the acceptable value for the paper clips is 1.14 grams.

An accurate value is the one which is close enough to the accurate answer and in case when the number of readings taken with in an experiment are close to each other then they are said to be precise.

Here the value obtained through three reading are close to each other hence, they are precise but none of these values is close to the acceptable value for the paper clips.

Hence, option B is correct.

c.           is the correct answer

not always but somethings can be reproduced in a laboratory.
