An independent-groups design is also known as a between-subjects design because participants are assigned to different groups, and each group is tested under a different condition, treatment, or stimulus. This type of design is used to compare two or more groups on a variable of interest. In contrast, a within-groups design (also known as a repeated-measures design) involves testing the same group of participants under all conditions, treatments, or stimuli. A matched-groups design is a variation of the independent-groups design, in which participants are matched on certain variables before being assigned to different groups. Finally, a mixed design combines both independent-groups and within-groups designs, typically by having one or more between-subjects factors and one or more within-subjects factors.
