How does Branch logic differ from Display Logic?

Branch logic and display logic serve different purposes in survey design. Branch logic is primarily used to determine the pathway or flow of the survey by showing or hiding entire blocks of questions based on respondents' previous answers. This allows researchers to create a tailored experience for participants, guiding them through the survey in a way that is relevant to them. For instance, if a participant answers a question in a certain way, branch logic can direct them to a specific block that is pertinent to their response, while skipping blocks that are not relevant.

On the other hand, display logic is applied to individual questions, allowing specific questions to appear or be hidden based on respondents' prior responses. This functionality is more granular and focuses on question-level visibility rather than entire blocks of the survey.

This distinction highlights why the correct answer emphasizes that branches manage entire blocks, while display logic operates at the individual question level. The other options present incorrect or misleading information regarding the scope and functionality of branch and display logic in survey design.
