The best way to describe the data collected from the digital scale is:

The precision is high, but the accuracy could be improved.

Explanation:

  • Precision refers to the consistency of the measurements. Since all five measurements are the same (4.9 kg), they are precise.
  • Accuracy refers to how close the measurements are to the true value. The true weight of the block is 5.0 kg, and the measurements (4.9 kg) are consistently off from that true value, indicating that the accuracy could be improved.
