This problem is checking for your understanding of the ideas: "Precision" and "Accuracy".

I have attached a helpful picture to my comment that can help us visualize the meaning and differences between these two terms.

If the results are BOTH Precise AND Accurate, then we might see that all of the numbers should be very close or equal to the actual result.

If the results are only precise but not accurate, then we might see that all of the numbers are close to each other but far away from the actual result.

If the results are only accurate but not precise, then we might see that all of the numbers can be considered generally correct but not close to each other.

If the results are neither precise nor accurate, then we might see that the numbers are not close to each other AND not close to the result.
