What is one benefit of using matrix questions in Qualtrics?

Using matrix questions in Qualtrics provides the benefit of simplifying the display of related items. This format allows respondents to evaluate multiple items using the same set of response options, which not only streamlines the survey layout but also facilitates easier comparison of the items being assessed. In scenarios where multiple questions share similar scaling, a matrix question presents these items compactly, thus improving user experience and potentially increasing response rates. The design helps to reduce the amount of scrolling and clicking, making it more user-friendly while collecting data efficiently.

The other options do not capture the primary advantages of matrix questions. For instance, while open-ended responses allow for detailed feedback, they do not fit within the context of a matrix format, which typically uses predefined response scales. Similarly, enabling video responses is not a characteristic of matrix questions, and direct email distribution pertains to survey administration rather than question format or design.
