Descriptive analysis is one of the most common forms of sensory testing. Descriptive methods are used to measure the type and intensity of attributes in a product. Thus, these methods require the respondent to describe a product in terms of its characteristics and to measure the intensity of those characteristics using scaling procedures. Although some attributes are fairly simple and can be measured easily by almost anyone, real understanding of a product's specific characteristics and the strength of the attributes requires the use of respondents trained to describe sensory stimuli and to measure intensity of perception.
