Hedonic Rating
In this test the assessor is asked to record the extent of liking for a product, usually by selecting a category on a "hedonic" or liking scale that runs from "extreme like" to "extreme dislike". A number of different scales have been developed and used. A very popular scale is the following nine - point hedonic scale:
