摘要
运用配对T检验和灰色关联性分析两种方法分析了评酒员间评价结果的差异性,同时根据Kendall协调系数W-检验和标准差分析了评价结果的可信度.结果表明:评酒员的评价结果存在显著性差异,得到了第二组评酒员评价结果更可信的评价结果.
In this paper,the difference of the sensory evaluation between difference tasters was analyzed using the paired T-test and grey relational grade analysis,and the reliability of the evaluation results was analyzed using Kendall coordination coefficient W-test and standard deviation.The test results showed that there was significant different between the two evaluation groups,and the second group evaluation is more reliable.
