Rating, ranking, or both? A joint application of two probabilistic models for the measurement of values
Following the debate between the proponents of the ranking and rating methods for the measurement of values, this article considers the hypothesis that a person’s responses in ranking and rating tasks are governed by the same unidimensional latent trait. The hypothesis was tested through a probabilistic modeling approach. The results of a joint application of the rating scale and ranking models indicated that this latent common trait exists and seems to have a role in molding the relationship between the latent variable and the observable responses in both ranking and rating formats.Back
