Z比分数在平板电视能效数据一致性核验中的应用

摘要

为打击能效虚标,提高能效数据一致性核验的评价能力,利用稳健统计Z比分数法描述测试数据.以平板电视的能源效率为例,介绍了Z比分数的构成、评价标准以及中位值、标准化四分位距等统计量的计算.结果表明,应用Z比分数进行能效数据一致性核验的数据统计处理,可以有效地识别能效备案实验室间存在的差异,提高能效检测的技术水平.%In view of false energy efficiency label,improving the evaluation of energy efficiency verification of data consistency,the robust statistical of Z-score method is used to describe testing data.Taking the energy efficiency of TV as an example,the component,evaluation criteria of Z-score,calculation of Median,Norm lnterquartile range and so on are discussed in this paper.The results prove that the application of Z-score in energy efficiency verification of data consistency,effectively identify the differences between the laboratory for energy efficiency,and improve the level of energy efficiency technology.
