What does an 'overall liking' score represent?

An 'overall liking' score is a key metric used in sensory evaluation that reflects a consumer's general preference for a product based on their sensory experience. This score aggregates responses to various sensory attributes such as taste, aroma, texture, and appearance, ultimately providing an indication of how much a consumer enjoys the product as a whole. This holistic assessment helps brands and researchers gauge consumer acceptance and guide product development.

The other options involve different aspects of product evaluation. For instance, a numerical rating of product cost pertains to the financial aspect rather than sensory preference. Ranking products focuses on comparison rather than individual preference, and a detailed analysis of sensory components might break down specific attributes but does not capture the overall sensation and satisfaction that contribute to an 'overall liking' score. Thus, the correct choice aligns perfectly with the concept of consumer preference derived from sensory evaluations.
