Publication Link 0


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.
