Correspondence between Mean and Median Scale Values for Sets of Stimuli Scaled by the Method of Equal-Appearing Intervals

Abstract

Mean scale values were computed for each of five sets of stimuli for which median scale values and the distributions of judges' ratings had been reported. The correlations (Pearson rs) between the mean and the median scale values for each of the five sets of stimuli range from .995 to .999. These high correlations indicate that mean and median scale values rank order sets of stimuli in approximately the same manner. Several implications of this finding are discussed.
