Which of the following is an advantage of unmoderated usability studies?

The choice highlighting the advantage of unmoderated usability studies focuses on the aspect of privacy. In unmoderated studies, participants complete tasks on their own without direct observation or interaction with a facilitator. This setup allows users to engage with the product in their own environment and at their own pace, often leading to more authentic feedback and behaviors. The privacy afforded by this method can make participants feel more comfortable and reduce the social desirability bias that might occur in moderated sessions where a facilitator is present.

In contrast, the presence of a facilitator in moderated studies can sometimes influence participant behavior, as users may alter their responses to align with perceived expectations. Therefore, the independent nature and the privacy of unmoderated studies can yield insights that are more representative of true user experiences.
