Validating the Sensitivity of the Beer Tetrad Test as Compared with the Beer Triangle Test (A Follow-Up Study): An American Society of Brewing Chemists Technical Committee Report
Journal of the American Society of Brewing Chemists ( IF 1.3 ) Pub Date : 2019-06-21 , DOI: 10.1080/03610470.2019.1619323

Abstract Previous testing by the sensory subcommittee confirmed that the Tetrad Test was more sensitive than the Triangle Test on beer samples with higher Effect Sizes. The subcommittee also wanted to confirm that the Tetrad Test was equally effective for samples with lower Effect Sizes; therefore, a new study was designed to validate the sensitivity of the Tetrad Test for smaller d’ values. The results of the second study show that for samples with smaller d’ values, the Tetrad Test resulted in a 15% reduction in d’ compared with the Triangle Test. This is less than the theoretical 1/3 reduction, indicating that the Tetrad Test is more sensitive. The Tetrad Test also resulted in a higher proportion of correct responses, though the difference was not significant at the 95% confidence interval. The subcommittee recommended that the Tetrad Test method be included in the ASBC Methods of Analysis.

验证啤酒四元组测试与啤酒三角测试相比的灵敏度(后续研究):美国酿酒化学家协会技术委员会报告

摘要 感官小组委员会先前的测试证实,对于效应量较高的啤酒样品,四元组测试比三角测试更敏感。小组委员会还想确认四分体检验对于效应量较低的样品同样有效;因此,设计了一项新研究来验证 Tetrad 测试对较小 d' 值的敏感性。第二项研究的结果表明,对于 d' 值较小的样品,与三角形测试相比,四元组测试导致 d' 减少了 15%。这小于理论值的 1/3 减少,表明 Tetrad 测试更敏感。Tetrad Test 也导致更高比例的正确响应,尽管差异在 95% 置信区间不显着。
