Multiple Baseline Single-Case Experimental Design

Multiple baseline single-case experimental designs (SCEDs) provide a powerful and cost-effective framework for research aimed at exploring the effects of interventions. After first discussing SCED, this entry further explores the multiple baseline design, including its strengths and weakness. An example of SCED is also provided.

Single-Case Experimental Designs

SCEDs are unique in that they conduct experimental investigations with a single case or series of cases. A case might be an individual or a larger single unit like a business or school. These designs contrast common experimental designs (e.g., randomized controlled trials) that are conducted using large sample sizes, multiple groups (typically including a control group), and few conditions (i.e., one control condition and one experimental condition).
