요약	Pragmatic single-subject experimental design applies the logic of single-case experimentation — repeated measurement, baseline comparison, and phase manipulation — within real-world practice settings rather than controlled laboratories. It allows practitioners and clinicians to rigorously evaluate interventions for individual participants without requiring large samples, making it especially valuable in applied, clinical, and educational contexts where heterogeneity across individuals is high.	The ABA design is a single-subject experimental design that demonstrates experimental control through three sequential phases: a baseline phase (A1), an intervention phase (B), and a return-to-baseline withdrawal phase (A2). By removing the intervention in the final phase and observing whether behavior reverts toward baseline levels, researchers establish a functional relationship between the treatment and the target behavior for an individual participant.
