Traditional sensory difference tests demonstrate whether a difference exists or not between two flavors; to determine the degree of difference requires further scaling. The two processes can be combined for perceptually small differences using difference tests based on signal detection measures. Such measures provide a measure of degree of difference directly which being a probability value is susceptible to analysis by parametric statistics Traditional signal detection measures are complex and time consuming but the present paper outlines a short and simple means of calculating such measures.
