Abstract Choosing a discrimination test can involve numerous factors, one of which is statistical power. The tetrad test has been shown to possess statistical advantages over the more traditional triangle method. However, these statistical advantages may not be present when the effect size decreases by more than 1/3. The frequency of large decreases in effect size, as well as other measures of test performance has not been characterized. In this study, over thirty products were tested using both triangles and tetrads in order to compare the two methods. The products tested ranged from canned vegetables and fresh fruits to deli meats and baked goods. After testing, inconsistencies were found within and across product categories. Only 16% of the tests were found to end with a different conclusion regarding a statistical difference (p

三角形和四元组判别方法的应用比较

摘要 选择辨别测试可能涉及许多因素，其中之一是统计功效。与更传统的三角形方法相比，四分体检验已被证明具有统计优势。然而，当效应量减少超过 1/3 时，这些统计优势可能不存在。效应量大幅下降的频率以及其他测试性能指标尚未表征。在这项研究中，为了比较这两种方法，使用三角形和四分体测试了 30 多种产品。测试的产品范围从罐装蔬菜和新鲜水果到熟食肉类和烘焙食品。测试后，发现产品类别内和产品类别之间存在不一致。发现只有 16% 的测试以关于统计差异的不同结论结束（p
