What should be defined after creating a questionnaire in an In/Out test?

Defining the pass rate after creating a questionnaire in an In/Out test is crucial because it establishes a benchmark for evaluating the results of the sensory assessment. The pass rate indicates the percentage of panelists' responses that must meet predefined criteria for the test to be considered successful. This allows for a clear interpretation of how well the product performs against the expected sensory attributes.

Setting an appropriate pass rate helps ensure that the results are meaningful and can guide decision-making processes in product development or quality control. It is essential for determining whether the product being tested meets the sensory criteria established before the assessment began.

The other options also play significant roles in the testing process, but they do not specifically provide the framework for evaluating the results of the questionnaire, which is the primary focus after its creation.
