Abstract

Does the inherent slight unreliability of extracting data from single-case experimental design studies have an impact on effect measure calculations? In this poster, we discuss results from a study comparing effect measures calculated with student behavior intervention data extracted from the same graphical displays using plot digitizing software by different researchers. Researchers interested in single-case experimental designs, replication of findings, and/or meta-analysis will learn about how the slight unreliability of extracted data minimally impacts effect measure calculations.
