Discrete Choice Experiments<\/h2>\n

\"SoftwareSetting up a discrete choice experiments in QuestionPro is not a complicated procedure. However, Discrete Choice Modeling and setting up a Discrete Choice Experiments requires you to be more focused on your project\u2019s goals. This translates into having a pre-determined set of attributes and levels that have been vetted internally before being exposed to the market. The Discrete Choice question type is located under the Advanced Questions tab as a part of conjoint models.<\/p>\n

To get our Discrete Choice Experiments started, we need to specify the Header\/Instructions; Features and Levels; Tasks; Concepts per Task and whether or not to offer a \u201cNo Choice\u201d option.<\/p>\n

Your instructions should be clearly written and as concise as possible. Set reasonable expectations for your respondents by telling them that there will multiple tasks and that they should consider each task independently.<\/p>\n

This screen allows you to specify both the features (aka attributes) and a number of levels per feature. Expect to set between 4 and 7 features. Prior survey or qualitative work can help establish both the features and levels to be used. Chris Diener, Ph.D. in his work suggests between 4 and 20 tasks depending on the complexity of the product or service. Another research suggests that after 15 tasks the number of dropouts goes up significantly.<\/p>\n

It is necessary to establish the number of concepts seen on each task (screen). Three, plus a \u201cno choice\u201d option is practical and minimizes cognitive overload. The no choice option brings a sense of realism as it allows the respondent to express the opinion that none of the options on a task would meet their needs.<\/p>\n

Features (attributes) need to be assigned one of three attribute types:<\/p>\n
