Nonequivalent group design is a quasi-experimental design where the researcher cannot randomly assign individuals to treatment groups. The individuals in the groups are already established based on some pre-existing characteristic, making random assignment impossible. In contrast, all other options (between-subjects, within-subjects, and pre-post designs) involve random assignment of participants to treatment conditions.
