The book highlights the different methodologies that can be applied and how to select the correct methodology based on the type of study you are performing, be it product research and development, quality control or consumer acceptance studies. Written by an experienced team of statisticians and sensory and consumer scientists, the book provides both academics and industry professionals with the first complete overview of a topic of ever-increasing importance Bibliography Includes bibliographical references and index Notes Online resource; title from PDF title page (EBSCO, viewed February 28, 2018) Subject Commercial products -- Testing.
