NASA-HDBK-8739.19-3, NASA HANDBOOK: MEASUREMENT UNCERTAINTY ANALYSIS PRINCIPLES AND METHODS: NASA MEASUREMENT QUALITY ASSURANCE HANDBOOK – ANNEX 3 (13 JUL 2010)., The analysis methods outlined in this document provide a comprehensive approach to estimating measurement uncertainty. Basic guidelines are presented for estimating the uncertainty in the value of a quantity for the following measurement alternatives: * Direct Measurements – The value of a quantity is obtained directly by measurement and not determined indirectly by computing its value from the values of other variables or quantities. * Multivariate Measurements – The value of the quantity is based on measurements of more than one attribute or quantity. * Measurement Systems – The value of a quantity is measured with a system comprised of component modules arranged in series. The structured, step-by-step uncertainty analysis procedures described herein address the important aspects of identifying measurement process errors and using appropriate error models and error distributions.
