Conjoint extension

The ESC’s Conjoint Extension makes it possible to generate and implement adaptive conjoint analyses (ACA) in web-based surveys. At each survey stage, the participant is faced with a choice of two response options. On the basis of the responses given, the software calculates which questions and response options should be presented to the respondent at the next stage. The respondent’s preferences are ranked during the course of the survey. In this way, for example, price and product preferences can be determined.
