What is "display logic" primarily used for in Qualtrics surveys?

Display logic in Qualtrics surveys is primarily used to conditionally show or hide questions based on the responses given by participants. This functionality allows survey creators to tailor the respondent's experience, presenting only the questions that are relevant to them based on their prior answers. For instance, if a respondent indicates they do not own a vehicle, logic can be applied to skip questions related to vehicle ownership, thereby enhancing the relevance of the survey and improving response rates.

Using display logic can also help in collecting cleaner data, as participants are not overwhelmed with irrelevant questions, which may lead to frustration or disengagement. By utilizing this feature effectively, survey designers can ensure that the flow of questions makes sense and is appropriate for each individual respondent.

In contrast, combining similar questions focuses more on streamlining the survey structure rather than conditional displaying of questions. Formatting the survey appearance relates to the visual aspects of the survey rather than the question logic, while randomizing question order is about the sequence in which questions are presented, rather than their visibility based on prior answers. Display logic, therefore, plays a crucial role in customizing and optimizing the survey experience based on respondent feedback.
