The Tetrad Test: Looking Back, Looking Forward

摘要: Until recently, the tetrad test was considered an interesting idea but seldom used. It not until Ennis and Jesionka revisited topic of power for discrimination tests, that it observed had, theoretically, considerably more than triangle test. This made a suitable candidate as replacement low powered, yet commonly used, method. has sparked lot activity concerning there will be to come. Yet, had been explored beforehand, purposes testing Thurstonian models. Had authors right tools, could they have produced any evidence support Jesionka's observation? Practical Applications The use difference tests where attribute change is described judge, especially useful consumers in normal conditions consumption. In such conditions, unlike those two-alternative forced choice (paired comparison), no person nearby specifying nature should attended while consuming food samples. The between samples discovered by consumer. Available like or duo-trio are statistically powerful therefore require large data, which can incur greater expense. theoretically these thus worthy of, indeed receiving, further investigation.
