Preference Testing

Abstract

Preference testing refers to consumer tests inwhich the consumer is given a choice and asked to indicate their most liked product, usually from a pair. Although these tests appear straightforward and simple, several complications are encountered in the methods, notably how to treat replicated data and how to analyze data that include a “no-preference” option as a response. Additional methods are discussed including ranking more than two products, choosing both the best and worst from a group, and rating the degree of preference.
