Statistical versus Artificial Intelligence Based Processing of Subjective Test Results
A comparison of both statistical and nonstatistical methods applied to the processing of the results of subjective testing is presented. Some principles underlying the use of statistical methods applied to acoustical evaluations are reviewed. Some exemplary data derived from listening tests are processed using parametric, nonparametric, and rough sets based methods. Conclusions concerning both statistical and nonstatistical approaches to the processing of acoustic data are discussed.
