Question

BlackTom AI · Accepted Answer

Hedonic tests measure consumers’ degree of liking or pleasure for a product, so the correct answer is “How much do you like the product?”

1. Relevant knowledge points and concepts
- Sensory evaluation is divided into three main types: discriminative (difference) tests, descriptive (attribute) tests, and affective (hedonic) tests. 
- Hedonic (affective) tests assess consumer acceptance and liking, commonly using scales such as the 9-point hedonic scale (“like extremely” to “dislike extremely”) or simple liking/preference ratings.
- Discriminative tests (triangle, duo-trio, paired comparison) assess whether samples differ; preference tests ask which sample is preferred.

2. Step-by-step reasoning
- Examine each option and map it to the sensory-evaluation type:
  - “How much do the samples differ?” asks about magnitude of difference — relates to discriminative/descriptive methods but is not the main hedonic question.
  - “Which product do you prefer?” is a preference test (a form of affective testing that elicits choice), but it asks for a relative choice, not the degree of liking.
  - “Are the samples different?” is a standard discriminative question (yes/no difference).
  - “How much do you like the product?” directly asks for degree of liking — the core of hedonic testing.
- Therefore the only option that directly corresponds to hedonic/affective evaluation is the liking question.

3. Calculations
- No numerical calculations are required for classification; hedonic data may later be analyzed statistically (mean liking scores, ANOVA), but none are needed to identify the test purpose.

4. Why the correct answer is correct
- Hedonic tests are designed to quantify consumer acceptance and liking intensity. Asking “How much do you like the product?” elicits that intensity directly, typically via a hedonic scale, which is the defining characteristic of hedonic testing.

5. Why the other options are incorrect
- “How much do the samples differ?” and “Are the samples different?” are difference/discriminative test questions, not hedonic. 
- “Which product do you prefer?” is a preference question (choice-based), not the same as measuring the degree of liking on a scale.

6. Conclusion
The correct answer is “How much do you like the product?” — this matches the provided answer.
