Abstract
Three taste test expts. were designed to test the appropriateness of a model for incomplete block rank analysis with paired comparisons. In one expt. the treatments consisted of two solutions, sucrose in tap water and lactose in tap water, each at four different levels of sweetness. In the second expt., lactose was replaced by sucrose plus quinine sulfate, sodium chloride and tartaric acid. In the third expt. four different solutions, using the same compounds in different proportions, were prepared to represent the sweet, bitter, sour and salt taste stimuli. Goodness of fit tests and other comparisons gave little or no indication of any inadequacy in the model.
