Evaluation of the Reliability and Validity of Graphclick as a Data Extraction Program
Reliability; Validity; Data extraction; Software testing
Data extraction programs are used to obtain approximations of raw data from published graphs. Quantitative syntheses of single-subject data require that researchers have access to valid and reliable data extraction programs. Authors analyzed the reliability and validity of a data extraction program, GraphClick.
