14 lis 2014 · The document also covers uncertainty ranges, significant figures, absolute and percentage uncertainties, and how uncertainties are treated in calculations. It provides examples of plotting graphs and determining the line of best fit.
Revised version of ISO 19036 offers a pragmatic approach to MU in quantitative food chain microbiology choice left between. Comprehensive approach with 3 components: technical, matrix and distributional uncertainties. Simplified approach: MU restricted to technical uncertainty.
22 lip 2019 · The document outlines methods of calculating uncertainty using the standard deviation, and explains why assessing uncertainty is important for interpreting results and ensuring measurement quality. Measurement uncertainty is a key component of any measurement result.
Measurement uncertainty = Defines the uncertainty in the measurement result due to random error. These are presented with error limits +/- ts, where t is a multiplier based on chosen confidence level and random error, s is the estimate for standard deviation.
When you know the uncertainty in a measurement, then you can judge its fitness for purpose. Understanding measurement uncertainty is the first step to reducing it.
The course will cover topics such as definition of uncertainty, types of measurement uncertainty, estimation of type A and type B uncertainties, combined and expanded uncertainty, coverage factors, probability distributions, best measurement capability, quality control charts, and case studies.
