Single-case research designs (SCRDs) are rigorous methods used to investigate the effects of interventions on socially important outcomes. A hallmark of SCRDs is repeated measurement of observable behavior presented in time-series graphs. The construction of time-series graphs can inflate Type I or Type II errors made via visual analysis. In the current investigation, we included all SCRDs published in four flagship journals in the field of learning disabilities ("Journal of Learning Disabilities," "Learning Disabilities Quarterly," "Learning Disabilities Research & Practice," "Journal of Learning Disabilities: A Contemporary Journal") over the last decade. A total of 47 studies including 315 graphs were included. Our findings suggest that ordinate scaling was appropriate across a majority of graphs; graphs, however, did not adhere to recommendations for x:y ratio or DPPXYR.
