  • DIFFERENCE TESTING - The Institute for Perception


In this 1-day course, we will discuss difference testing theory and practice, and provide practical examples to illustrate the methods. We will explain why the tetrad test may require as little as 1/3 the sample size needed for the triangle test and also show how to establish a consumer relevant sensory difference.
