Abstract A method of controlled experimentation is developed for operationally defining and measuring qualitative variables and validating these measures. Hypothetical vacation trip scenarios were generated by varying the distance to be traveled, air fare, driving cost, number of travelers, and season. For each scenario, respondents rated the comparative economy, safety, and desirability of flying and driving. Responses were analyzed to determine how each qualitative variable varies as a function of the manipulated attributes, to determine the interrelationships between the qualitative variables, and to examine the relationship between the qualitative variables and overt behavior.
