Detailed explanation-1: -A within-subjects design is also called a dependent groups or repeated measures design because researchers compare related measures from the same participants between different conditions.

Detailed explanation-2: -A repeated-measures design is one in which multiple, or repeated, measurements are made on each experimental unit. The experimental unit could be a person or an animal, and repeated measurements might be taken serially in time, such as in weekly systolic blood pressures or monthly weights.

Detailed explanation-3: -In a within-subjects design, each participant experiences all conditions, and researchers test the same participants repeatedly for differences between conditions.

Detailed explanation-4: -Within-subjects (or repeated-measures) study design: the same person tests all the conditions (i.e., all the user interfaces).

Detailed explanation-5: -A matched pairs design is a type of experimental design wherein study participants are matched based on key variables, or shared characteristics, relevant to the topic of the study. Then, one member of each pair is placed into the control group while the other is placed in the experimental group.
