Does inter-subject variability depend on test material?
STEFAN S. WINKLER · 2014
Quality of experience (QoE) research usually focuses on measuring or predicting mean opinion score (MOS), i.e. the average of ratings across subjects. Here we focus instead on the variability among subjects and explore questions such as: What factors does it depend on? Are these factors consistent across different experiments? Could variability be predicted from the test content?
