DISCREET CHOICE EXPERIMENT

Introduction

The Discrete Choice Experiment (DCE) is a powerful survey methodology that presents respondents with a series of hypothetical scenarios, each containing different attribute combinations. Respondents must choose their preferred option, allowing researchers to analyze decision-making processes and understand preferences.
With Chisquares, setting up a DCE is intuitive and flexible, enabling you to define key attributes, configure choice sets, and collect high-quality preference data.
This manual will guide you through the process of setting up and managing a Discrete Choice Experiment question, including advanced customization options.
