Abstract
The application of the paired comparison method in skin feel testing of emulsion-based skincare products is important.Combining two examples of sensory testing of body lotions,the design logic,key implementation points,and data interpretation strategies of this method in different research scenarios were explored systematically.Through the in-depth analysis of test design,this study focused on the impact of including or excluding the"equal option"on the test results,and proposed a decision framework based on research objectives,participant characteristics and resource constraints to guide practical application.In similarity testing scenarios,such as the production line consistency verification that require precise identification of subtle differences,the sample size is set to 80 people at a 95%confidence level.The research results show that a mandatory selection design without the"equivalent options"can significantly improve the statistical power,ensuring the reliability and validity of the results.Conversely,in the difference testing scenarios such as formulation upgrade evaluation that requires a true reflection of consumer decisions,with a sample size of 95 at a 95%confidence level,including"equivalent options"can effectively avoid conclusion bias and provide evaluation results closer to actual consumer perceptions.Through the rational application of the paired comparison method,researchers and practitioners in the industry can improve product quality and enhance consumer satisfaction,consequently occupy a favorable position in the fiercely competitive market environment.关键词
