Single-subject research designs repeatedly measure behavior within one participant or unit across baseline and intervention phases so researchers can evaluate whether a treatment is associated with a clear behavior change.

Single-Subject Research Designs

In single-subject research, data analysis typically differs from group research by relying heavily on visual inspection of individual data rather than averaging across participants and using inferential statistics. This approach involves graphing participants' data to visually detect changes and judge treatment effects. While formal statistical methods are sometimes used as a supplement, they do not replace visual inspection.
