针对葡萄酒评价结果的差异性及可信度问题,在已知两组红白葡萄酒在各个指标上评分的前提下,首先分别在整体上和单个指标上对两组评分进行非参数检验,可以得出结论:细节指标可能因为抽样人群的偏好性具备显著性差异但是在整体中差异将会被淹没.为了体现单个指标之间的差异性,再对各个样品酒进行模糊综合评价,从得出的两组评分集可以看出其评分存在分歧.最后提出了运用格拉布斯准则判断可信度的方法.“,”according to the discrepancy and reliability of grape wine evaluate results, under the circumstance of knowing the score on different index of two groups of red and white wine,fistly using non-parametric test to grade two groups on the whole and single index respectively,a conclusion is put forward: details indicators may have significant difference because of sampling crowd partial temper,but in the whole the difference will be flooded.Secondly, using fuzzy comprehensive evaluation to each sample wine in order to reflect the individual differences between the index,the bifurcation is found from the two groups score set.Finally grubbs criterion was used to judge the reliability.
