摘要
能力验证样品的均匀性和稳定性评价是能力验证活动中最基础的一个环节,用单因素方差分析法判定均匀性和t检验法判定稳定性是两种最常见的方法。本文从统计学的角度对两种判定方法进行了解释,希望对能力验证组织实施有一定的借鉴指导作用。
The homogeneity and stability of Sample are the most basic steps for proficiency testing programs.one-factor analysis of variance and t-test are the most common methods to evaluate the homogeneity and stability,these two methods were discussed and explained by using statistical techniques in this paper,which provides guidance for the proficiency testing program.
