Explanation:

Between-subjects design: The between-subjects design is also referred to as between-groups design and is one of the types of experimental design. In a between-subjects design, a single participant is exposed to only one user interface because each participant is supposed to test a single condition. It means that a single participant will experience one experimental condition.

Example: A researcher has two different groups of participants, one group is being experimented in a warm condition and the other is in cold condition.
