MEASUREMENT
UNCERTAINTY BUDGETS
This in-depth workshop covers the basics of
measurement uncertainty analysis including uncertainty
components, simple statistics, statistics on the calculator,
combining uncertainties, control charts, GUM (Guide to the
Uncertainty of Measurements) and analysis of uncertainty
budgets, complete with examples and problems. This workshop
presents a combination of lecture and classroom written
exercises to demonstrate the principles of measurement
uncertainty analysis.
