A Type A evaluation of uncertainty is one made

  • A.by assuming the uncertainty is negligible
  • B.from the statistical treatment of repeated observations
  • C.from a calibration certificate or a manufacturer's specification
  • D.by the judgement of the person taking the measurement

Answer: B

Repeating the measurement and computing the standard deviation of the mean is the Type A route, and everything else, from certificates to handbook data to reasoned judgement, is Type B. The distinction concerns how the figure was obtained rather than its quality.
