Revision of E1958-19a Standard Guide for Sensory Claim Substantiation


None Provided


Section 14.2.1 provides guidance related to the statistical test for a superiority claim: the type of statistical test, the allocation of ties, the test statistic, and the threshold for making a qualified vs. an unqualified claim. Within this paragraph, the scope of the following statement is ambiguous: Other analytic approaches may be appropriate, but require justification. In this section (related to superiority claims), the relatively broad scope of this statement is not communicated as effectively as it is in other sections (equivalence, unsurpassed).
