Abstract
Single-case design (SCD) research is an experimental approach for analysis of an effect between an independent variable and dependent variable. Traditionally, analysis of effect for SCD has relied on visual analysis, an approach whereby a trained observer analyzes a visual display of the data. Recent advances in statistical approaches have been forwarded for SCD research in the literature to assist in the interpretation of intervention effects. This review outlines the logic of SCD and describes the varied approaches for the analysis of effect in SCD research.
