7. Types of tests for recipe optimization

7.6. Example: Popularity Test

A popularity test is used to test whether a change has improved or worsened a product.
The test can be done for individual samples or for a range of samples, but they are all judged individually.
The judging can be for the overall liking of a product and/or for certain atributes of the product, e.g. the fragrance of the product.
Like or dislike is expressed on a scale of 1 - 9, whereby:
1 = dislike extremely
2 = dislike very much
3 = dislike moderately
4 = dislike slightly
5 = neither like nor dislike
6 = like slightly
7 = like moderately
8 = like very much
9 = like extremely
