Visual Display of Graphic Data in Single Case Design Studies: Systematic Review and Expert Preference Analysis
Ledford, Jennifer R.; Barton, Erin E.; Severini, Katherine E.; Zimmerman, Kathleen N.; Pokorski, Elizabeth A.

Two studies regarding the graphic display of single case data are presented. First, measurement and graphical display of data from studies in highly-ranked journals in special education were assessed. Measurement of desirable behaviors rather than undesirable behaviors was common and most studies used sessions and percentages as x and y-values, respectively. Data presentation (graph ratios and number of data points and sessions per cm) was highly variable; average ratios did not align with previously-published recommendations. In the second study, 50 editorial board members of special education journals were surveyed to determine preferences for graphing ratios. Preferences did not align with recommended graphing practices and varied based on the number of sessions depicted on the graph.
