摘要

描述了一种简单的图形显示，用于调查具有报告不确定度的实验室间数据之间的一致性。该图由一致性测量组成——两两显著性差异检验的显著性水平，对多重比较进行调整——绘制为图像，其中显著性由颜色或强度表示。这提供了一种易于解释的图形表示，可以判断一致的程度，并且可以很容易地看到异常。讨论了图的构造，并注意在检查异常时对数据集大小的调整选择。讨论了误差条目视检测的优点，并给出了计量比较的一些实例。

Consistency plots: a simple graphical tool for investigating agreement in key comparisons

A simple graphical display is described for investigating agreement among interlaboratory data with reported uncertainties. The plot consists of a measure of agreement—the significance level of a test for significant pairwise difference, adjusted for multiple comparisons—plotted as an image in which significance is represented by colour or intensity. This provides an easily interpretable graphical presentation in which the degree of consensus can be judged and in which anomalies are easily visible. The construction of the plot is discussed, with attention to the choice of adjustment for the size of the data set in checking for anomalies. The advantage over visual inspection using error bars is discussed, and some examples from metrology comparisons are presented.

期刊介绍： Accreditation and Quality Assurance has established itself as the leading information and discussion forum for all aspects relevant to quality, transparency and reliability of measurement results in chemical and biological sciences. The journal serves the information needs of researchers, practitioners and decision makers dealing with quality assurance and quality management, including the development and application of metrological principles and concepts such as traceability or measurement uncertainty in the following fields: environment, nutrition, consumer protection, geology, metallurgy, pharmacy, forensics, clinical chemistry and laboratory medicine, and microbiology.
