Abstract This paper reports the corrected findings of a study that compared two purchase probability scales in a Web based survey: a pull-down version of the Juster Scale, and a written version of the Verbal Probability Scale. Respondents were recruited via a newsletter sent to clients of a local Internet provider, and directed to a Web site for the survey, where they were randomly assigned to a treatment group. In one task, respondents were asked to use a version of the probability scale to indicate the likelihood of choosing each of five billing options. The two forms of the scale produced similar estimates, a finding consistent with previous research. In a second task, respondents were asked to give the probability of using two services. A different price was used with each of four treatment groups, for each form of the probability scale. For both services, the Juster Scale elicited much lower probability scores than did the Verbal Probability Scale, at each price. As the options and services were not actually implemented, it is not possible to say which form of the scale produced the most accurate estimates.
