Ambiguous meanings are expressed by means of verbal probabilistic terms rather than numerical ones, and several methods have been developed for measuring the meanings of probability terms directly. We proposed a new indirect method to measure the probability implied by such terms. An indirect measurement was based on the method used by the experiments of Tversky & Fox (1995). We applied the direct and indirect methods to measure the meanings of terms, and validated the new methods. Finally, the differences between the indirect and the direct measurement methods were discussed. We found that in indirect method subjects evaluated the probabilistic terms more literally than in direct method.
