The usefulness of conjoint analysis does not end with the collection of accurate preference information.

Frequently, researchers will define screeners at the beginning of the survey to ensure pertinent opinions are gathered. Since there are four combinations in total, a monadic design will need four cells. Unlike a direct rating of the importance of each attribute in isolation, conjoint analysis forces trade‐offs in the importance of the different attributes.

The traditional choice based approach typically calls for two choices, and has the respondent choose between option A and option B. If you don’t test a variable, you will get zero vision into its preference, but testing too many features and levels can lead to respondent fatigue, inconsistent responses, and worthless data.

Assuring that the respondent is fully  informed on the packages they will be selecting amongst is a must within conjoint analysis. Here’s an equation Sawtooth Software uses to determine the number of responses: Number of respondents = (multiplier*c)/(t*a), c = largest number of levels across all features, a = number of alternatives or choices per question. Design experiences tailored to your citizens, constituents, internal customers and employees. “A picture is worth a thousand words” can ring true in conjoint analysis.

With data in hand, a simulator can be utilized to capture the what-ifs of making changes to the attributes. When a conjoint study is conducted, it is usually the focus of the survey, but not the entirety of it. Qualtrics specifically uses a Multinomial Logistic Regression model. If price was included within the attribute set, the simulator can be an outstanding tool for inferring that value. … In the most straightforward approach, respondents could be asked how much they value the components of a product – that is, how much they like the features (benefits) and how much they are willing to pay (costs).

There shouldn’t be one level that is shown in six bundles, while another level is only included in one bundle. Experimental designs in conjoints maximize the number of data points and the coverage across potential packages, while minimizing the number of profiles we expose to the respondent. Let’s say dark chocolate was shown ten times and picked eight times, while milk chocolate was picked two out of ten times. The clearer a package is to the survey-taker, the truer the resulting utilities will be. Once the … Keep in mind that the more features and levels you include, the more difficult and overwhelming the conjoint will be for the respondents.
