সারসংক্ষেপ	The Pragmatic AB Design is a single-case experimental design that collects repeated measurements of one individual or unit across two consecutive phases: a baseline phase (A) with no intervention, followed by an intervention phase (B). Deployed in real-world, clinically feasible conditions rather than tightly controlled laboratory settings, it is widely used in behavioral health, rehabilitation, education, and applied psychology to generate actionable evidence about individual-level treatment effects.	The AB design is the simplest single-subject experimental design, consisting of two sequential phases: a baseline phase (A) in which the target behavior is observed under natural conditions without intervention, followed by an intervention phase (B) in which the treatment or manipulation is introduced. Changes in the behavior's level, trend, or variability between phases are used to infer the effect of the intervention on the individual participant.
