ANOVA tests whether independent variables affect listening-test outcomes
Evidence
Quite commonly analysis of variance (ANOVA) is used, which answers the question, ‘do any of the independent variables have an effect on the dependent variable?’ If an independent variable is found to have an effect, posthoc tests can then be used to measure how the independent variable affects the result. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 950
