Abstract

This Brief Guide reintroduces readers to the main concepts and technical tools used for the evaluation and expression of measurement uncertainty, including both classical and Bayesian statistical methods. The general approach is the same that was adopted by the Guide to the Expression of Uncertainty in Measurement (GUM): quantities whose values are surrounded by uncertainty are modeled as random variables, which enables the application of a wide range of techniques from probability and statistics to the evaluation of measurement uncertainty. All the methods presented are illustrated with examples involving real measurement results from a wide range of fields of chemistry and related sciences, ranging from classical analytical chemistry as practiced at the beginning to the 20th century, to contemporary studies of isotopic compositions of the elements and clinical trials. The supplementary material offers profusely annotated computer codes that allow the readers to reproduce all the calculations underlying the results presented in the examples.

测量不确定性简要指南（国际理论化学和应用化学联合会技术报告）

本《简要指南》向读者重新介绍了用于评估和表达测量不确定度的主要概念和技术工具，包括经典和贝叶斯统计方法。总体方法与《测量不确定度表达指南》（GUM）所采用的方法相同：将其值受不确定度影响的量建模为随机变量，这样就能将概率论和统计学的各种技术应用于测量不确定度的评估。书中介绍的所有方法都通过实例进行了说明，这些实例涉及化学和相关科学的多个领域的真实测量结果，从 20 世纪初的经典分析化学到当代的元素同位素组成研究和临床试验，不一而足。补充材料提供了附有详尽注释的计算机代码，读者可以重现示例中结果的所有计算。

期刊介绍： Pure and Applied Chemistry is the official monthly Journal of IUPAC, with responsibility for publishing works arising from those international scientific events and projects that are sponsored and undertaken by the Union. The policy is to publish highly topical and credible works at the forefront of all aspects of pure and applied chemistry, and the attendant goal is to promote widespread acceptance of the Journal as an authoritative and indispensable holding in academic and institutional libraries.
