Results of Duo-Trio Difference Test I
Results of the first duo-trio difference test for beer produced from hops exposed to different field stress levels are shown in the table below. To achieve significance, 20 panelists out of a total 30 had to correctly identify the sample that was different from a labeled reference out of a set of three (p ≤ 0.05). Panelists correctly identified the test (medium- or high-level stress) sample as different from the reference (low-level stress) sample for all pest treatments with the exception of the high-level powdery mildew, in which 19 of 30 panelists correctly identified the sample that was different. Note that reported results are for replication 1 only.
