Both the accuracy and precision are poor.

Answer 1

In this scenario, the digital scale consistently measures the block's weight as 4.9 kg, while the actual weight is 5.0 kg.

• Accuracy refers to how close the measured value is to the true value. Since the measurements are consistently below the true weight, the accuracy is poor.
• Precision refers to the consistency of the measurements. Since all five measurements are the same (4.9 kg), the precision is high.

Given this analysis, the best description of the data is:

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