Abstract

Based on the data related to the evaluation score of wine taster provided in 2012 CUMCM, this study firstly adopts confidence interval method to eliminate the effect of wine tasters’ personal differences. Then, by using analysis of variance, we make a test of significance on evaluation results of wine tasters from Group A and B at the significance level of 0.05. Results show that there is no significant difference in the sensory evaluation results of wine tasters from the two groups. By comparing the variance of comprehensive scores given by wine tasters from the two groups, we confirm the evaluation results of wine tasters from which group are more reliable. Results of the model shows that variances of evaluation results given by wine tasters from Group B are all smaller than that of Group A, which prove that evaluation result of wine tasters from Group B is more reliable.
