What is the main purpose of using branches in Qualtrics surveys?

The primary purpose of using branches in Qualtrics surveys is to direct participants to different survey paths based on their responses. Branching logic allows survey creators to customize the experience for respondents, ensuring that they only answer questions relevant to them. This not only makes the survey more efficient by avoiding unnecessary questions, but it also helps in collecting more accurate data by guiding respondents towards options and queries that are tailored to their previous answers.

In contrast, connecting to external applications involves integrating third-party services, which is not the primary function of branching. Enhancing the graphical interface pertains more to visual design elements rather than the logical flow of the survey. Generating automated summaries relates to post-survey analysis rather than the structure of the survey itself. Thus, branching serves a critical role in managing respondent experience and data collection through conditional survey pathways.
