Description

1.1 This document covers a procedure for determining preference between two products using a two-alternative forced-choice, which may or may not include the option of choosing no preference.

1.2 A paired preference test determines whether there is a statistically significant preference between two products for a given population of respondents. The target population must be carefully considered.

1.3 This method establishes preference in a single evaluation context. Replicated tests will not be covered within the scope of this document.

1.4 Paired preference testing can address overall preference or preference for a specified sensory attribute.

1.5 The method does not directly determine the magnitude of preference.

1.6 This method does not address whether or not two samples are perceived as different. See Test Method E 2164.

1.7 A paired preference test is a simple task for respondents, and can be used with populations that have minimal reading or comprehension skills, or both.

1.8 Preference is not an intrinsic attribute of the product, such as hue is, but is a subjective measure relating to respondents’ affective or hedonic response. It differs from paired comparison testing which measures objective characteristics of the product. Preference results are always dependent on the population sampled.

1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
