Measurement and Uncertainty

≈ 32 min

Measurements include resolution, calibration and uncertainty. Repeated readings reveal spread, while systematic error shifts results consistently.

Core checkpoint: Report only digits justified by the instrument and method.

Which statement best captures the core checkpoint for Measurement and Uncertainty?

Report only digits justified by the instrument and method.
