It can be said that the measurements of the students are precise but not accurate.
<h3>What is accuracy and precision?</h3>
Accuracy is the degree of conformity of a measure to a true or standard value while precision is the ability of a measurement to be reproduced consistently.
Simply put, measurements are said to be accurate when they are close to a true or standard value but are said to be precise when they are close to one another.
According to this question, a student measures the mass of 40 mL of a liquid 3 times and obtained the following mass readings: 28.5g, 28.4g and 28.2g.
Based on the measurement, the measured data are precise because they are close to one another but are not accurate because they are not near the standard value of 37.9g.
