Question

A digital scale is used to measure a block that has a weight of exactly 5.0 kg. Five measurements are recorded, and all of them provide a measurement of 4.9 kg. How could this data best be described?(1 point)

Answer 1

The correct response is: **The precision is high, but the accuracy could be improved.**

Explanation:
- **Accuracy** refers to how close a measurement is to the true value (in this case, 5.0 kg). Since all measurements recorded 4.9 kg, which is not close to the true weight, the accuracy is poor.
- **Precision** refers to the consistency of the measurements. Since all five measurements were the same (4.9 kg), this indicates high precision.

Thus, the measurements are consistently giving the same value (high precision) but are not close to the true weight (low accuracy).
