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:
- Like extremely
- Like very much
- Like moderately
- Like slightly
- Neither like nor dislike
- Dislike slightly
- Dislike moderately
- Dislike very much
- Dislike extremely
The categories on this scale are equally spaced and it is quite common for the data to be analysed by assigning the values 1 to 9 to the categories on the scale, and then assuming that the intervals are equal. With this assumption, the data can be summarized by recording average liking "Scores".
