SUMMARY

Experimenters involved with sensory difference tests have long used the triangle test as a basic procedure. In some circumstances, they have augmented the basic triangle test through obtaining “degree-of-difference” scores between the supposed odd sample and the pair of like samples. A companion paper gives a method of formally utilizing these scores in the analysis of these modified triangle tests when a computer is available. This paper summarizes the method and gives the results of applications of the modified triangle test to experimental data.
