Tests for simple difference and the triangle test are very useful methods for quality control and product development. Newly formulated products can be evaluated by determining if a simple difference exists between the new products developed and the old ones. Similarly, the hedonic scale rating can be used for internal factory testing, and this method is also suitable for market research by determining the consumer’s acceptance or preference for certain products.
