摘要: Choice questions are increasingly being used to scale competing natural resource programs. Respondents choose between two alternatives with varying levels of program characteristics and costs. Complexity in the choice task can increase randomness (variance) choices estimation preferences, magnitude is examined using scope tests parameters. We provide an empirical comparison response variance from three formats. A simple resource-to-resource format appears superior referendum composite formats terms coherence. The application stems a study addressing PCBcaused losses Green Bay, Wisconsin.
