If four students separately measure the density of a rock, and they all have very low percent differences between their measurements, what can you say for certain about the accuracy of their
results?

Their measured results are closer to the exact or true value. Hence, their measured value is considered to be more accurate.

Explanation:

Considering the situation described above, the accuracy of a measured value depicts how closely a measured value is to the accurate value.

Hence, since the students' measured values have very low percent differences, it shows the similarity of computations or estimates to the actual values, which in turn offers a smaller measurement error.

Therefore, their measured results are closer to the exact or true value, which implies that their measured value is considered to be more accurate.

are there answer choices to this question? this seems like a question where you have options to choose from.
