It is often necessary to conduct expensive, time-consuming experiments in order to obtain reliable information on product characteristics from consumer samples. This report investigates reducing product testing costs by improving measurement sensitivity. In some cases, such as when estimating sensory intensity differences, smaller samples could be used if sensitivity could be increased.
