Table of Contents

Quantitative Descriptive Approaches: When panelists rate products according to one single list of attributes. When products are rated according to one single list of attributes. When products are rated according to several lists of attributes. Qualitative Descriptive Approaches: When products are depicted by comments. When two different products are put in various experimental contexts. When products are grouped into homogeneous clusters. When products are positioned onto a projective map. Affective Descriptive Approaches: When products are solely assessed by liking. When products are described by both liking and external information "independently." When products are described by a mix of liking and external information. Appendices. Index.

Reviews

"Lê and Worch present students, academics, researchers, and statisticians with a quantitative, qualitative, and effective approach to sensory evaluation. The authors have organized the bulk of their text in three sections, devoted to quantitative descriptive approaches, qualitative descriptive approaches, and affective approaches, in turn. Individual chapters within these sections cover a variety of subjects, such as product rating according to a single list of attributes, product rating when depicted by comments, and product rating when solely assessed by liking."

"…a comprehensive and practical book written for sensory scientists. The book introduces techniques for the analysis of sensory data with a strong emphasis on multivariate analysis. Throughout the book, real data from a variety of sensory experiments are used to illustrate how to analyze sensory data appropriately using R. … The examples used in the book emphasize a good understanding of the objective of the experiment, the nature of the data collected and its statistical notation, how to implement the appropriate method of analysis using R, and how to read the output and carefully interpret the results. … Sensometrics is a dynamic and fast-moving field, yet books on how to analyze complicated sensory data are rare. This practical book is a valuable resource for scientists learning how to analyze sensory data appropriately. It can be used as a course textbook to teach new sensory scientists the full suite of existing statistical techniques, or as a reference handbook for the experienced sensory scientist seeking information on how to analyze a specific type of sensory data. … well-organized, easy to read, and provides practical instruction in statistical techniques for analyzing sensory data using R."
