Applying STRESS to Evaluate Variabilities in Consumer Responses in the Textile Industry
Abstract
The standardized residual sum of squares (STRESS) index has been employed to determine the goodness of fit between sensory and measured datasets. It has also been applied to determine inter- and intra-individual variability in repeated sensory evaluations. The primary goal of this work is to demonstrate the application of STRESS in the perceptual evaluation of textile products. Using case studies, the suitability of STRESS for evaluation of observer preferences of clothing colors was demonstrated. It was shown that the metric is a useful analytical tool for quantifying observer variability in perceptual assessments within the textile and apparel domains.
