Precision of Measurement in Sensory Difference Testing

Taught by Dr. John Ennis



In the evaluation of new incarnations of existing products, difference testing is among the most commonly used sensory techniques. Although difference testing is a classical technique, however, the science of difference testing continues to evolve. In particular, recent research advances have provided tools, techniques, and theory to quantify the error in the sensory measurement provided by all of the commonly used difference tests. In this webinar, we will cover how these advances inform business risk calculations, help with the determination of consumer-relevant action standards, and promise to unite equivalence and difference testing.

This webinar is intended for a general audience of sensory professionals and graduate students. No detailed technical knowledge is assumed.

A digital recording of this webinar is available for purchase ($289).
