Abstract This subcommittee was formed based on the recommendation of the American Society of Brewing Chemists (ASBC) sensory subcommittee. Its purpose was to determine if the Tetrad Test is as sensitive as the Triangle Test for beer sensory testing. To accomplish this task, 11 sensory panels participated in Tetrad and Triangle testing of two commercially available beers. Half of the samples were stored at 4 °C and the other half were stored at 24 °C. Samples, detailed instructions, and ballots were shipped to each of the participating panels. Each panel returned their results to the Wolf Group for data analysis. The Tetrad Test was found to be a suitable replacement for the Triangle Test. The Tetrad Test had a higher percentage of correct responses at more panel sites than did the Triangle Test. At a confidence level of 95%, no significant differences were observed in the aggregate proportion of correct answers for the Triangle Test versus the Tetrad Test. The reduction of Effect Size (d′) for the Tetrad was less than the theoretical reduction of 1/3, indicating that the Tetrad Test is slightly more powerful than the Triangle Test. The lower standard deviation of the Tetrad Effect Size indicates that it is more precise than that of the Triangle Test. The subcommittee recommended that the Tetrad Test Method be published in the ASBC Methods of Analysis as a suitable alternative to the Triangle Test. The subcommittee also recommended that further testing be conducted to test the tolerances of the Effect Size (d′).

与啤酒三角测试相比，验证啤酒四元组测试的灵敏度：美国酿酒化学家协会技术委员会报告

摘要 该小组委员会是根据美国酿酒化学家协会 (ASBC) 感官小组委员会的推荐成立的。其目的是确定 Tetrad Test 是否与用于啤酒感官测试的 Triangle Test 一样敏感。为了完成这项任务，11 个感官小组参与了对两种市售啤酒的 Tetrad 和 Triangle 测试。一半样品在 4°C 下储存，另一半在 24°C 下储存。样品、详细说明和选票被运送到每个参与小组。每个小组将他们的结果返回给 Wolf Group 进行数据分析。Tetrad Test 被认为是 Triangle Test 的合适替代品。与三角形测试相比，四分体测试在更多的小组站点上具有更高的正确响应百分比。在 95% 的置信水平下，Triangle Test 与 Tetrad Test 的正确答案的总比例没有观察到显着差异。Tetrad 的效应量 (d') 减少量小于理论减少量的 1/3，表明 Tetrad 测试比 Triangle 测试稍微更强大。Tetrad Effect Size 的较低标准偏差表明它比 Triangle Test 的标准偏差更精确。小组委员会建议在 ASBC 分析方法中公布四元组测试方法，作为三角形测试的合适替代方案。小组委员会还建议进行进一步测试以测试效应量 (d') 的容差。Tetrad 的效应量 (d') 减少量小于理论减少量的 1/3，表明 Tetrad 测试比 Triangle 测试稍微更强大。Tetrad Effect Size 的较低标准偏差表明它比 Triangle Test 的标准偏差更精确。小组委员会建议在 ASBC 分析方法中公布四元组测试方法，作为三角形测试的合适替代方案。小组委员会还建议进行进一步测试以测试效应量 (d') 的容差。Tetrad 的效应量 (d') 减少量小于理论减少量的 1/3，表明 Tetrad 测试比 Triangle 测试稍微更强大。Tetrad Effect Size 的较低标准偏差表明它比 Triangle Test 的标准偏差更精确。小组委员会建议在 ASBC 分析方法中公布四元组测试方法，作为三角形测试的合适替代方案。小组委员会还建议进行进一步测试以测试效应量 (d') 的容差。小组委员会建议在 ASBC 分析方法中公布四元组测试方法，作为三角形测试的合适替代方案。小组委员会还建议进行进一步测试以测试效应量 (d') 的容差。小组委员会建议在 ASBC 分析方法中公布四元组测试方法，作为三角形测试的合适替代方案。小组委员会还建议进行进一步测试以测试效应量 (d') 的容差。
