Abstract

Many methodologists claim that autocorrelation in intra-subject designs is a pervasive and critical problem necessitating complex statistical analyses to determine the existence of an intervention effect. In this study, autocorrelation, coefficients were found for a large sample of graphed data in the Journal of Applied Behavior Analysis. Results indicate that there is minimal, negative autocorrelation for most of the data analyzed (-.04). This result suggests the presence of autocorrelation in the intra-subject designs analyzed is of no practical significance, and thus is not the problem some methodologists have assumed it to be.
