Which type of usability test allows participants to complete tasks independently, such as from their home computers?

The choice of an unmoderated usability test is correct because this approach allows participants to complete tasks independently, often without real-time guidance from a facilitator. In unmoderated usability testing, participants can navigate the interface and complete designated tasks at their convenience, typically using their own devices in their natural environment, such as their home computers. This setup not only provides more authentic user behavior but also enables researchers to gather insights from a larger and more diverse group of users, as participants are not limited to a specific location or time frame.

While moderated usability tests involve direct interaction with a facilitator who guides participants through the tasks, unmoderated tests stand out by emphasizing independent user operation. Focus group testing is a different method that centers around discussions among participants and does not assess individual task performance. Remote usability testing can include both moderated and unmoderated formats but is specifically defined by the absence of physical proximity between the facilitator and participants, which could lead to confusion in selecting the most precise answer.
