A percent error value that is very small indicates what about the measurements?

• A. It is a rough estimate with no meaningful interpretation.
• B. It indicates accuracy of measurements and reliability of results.
• C. It has no relation to measurement quality.
• D. It guarantees perfect measurements.

Answer: (B)

Percent error shows how far a measurement is from the true value. When that percentage is very small, it means the measured value is very close to the accepted value, which indicates the measurement is accurate. If repeated measurements also have small errors, the results are consistent, showing reliability. So a very small percent error points to measurements that are both accurate and dependable, though it doesn’t guarantee perfection.
