Single-subject designs not only narrow the focus onto an individual and regularly measure student performance but also highlight the role of functional interventions and practicality of solutions with an emphasis on socially valid goals. First such designs can demonstrate clear causal relations between intervention and behavior change.

The results of Edgington designs permit a causal interpretation if the subjects cannot discriminate the different experimental conditions ie.

Researchers use single-subject design because these designs are sensitive to individual organism differences vs group designs which are sensitive to averages of groups.

Single-subject experimental designs SSEDs represent an important tool in the development and implementation of evidence-based practice in communication sciences and disorders. Single-subject experimental designs also referred to as within-subject or single case experimental designs are among the most prevalent designs used in CSD treatment research. If a true single-blind study is performed.
