Abstract:
This tutorial aims at discussing current practices of listening test evaluation. Topics to be covered are post-screening of tests results enabling to reject data from unreliable subjects and analysis of the results. This will cover parametric and non-parametric statistics, and the decision when which of these is necessary. Special emphasis will be set on which conclusions from the analysis are adequate from a mathematical perspective. This tutorial aims at providing researchers with a better understanding of the results of listening tests.
