Abstract
Reexamined the lag 1 autocorrelations of 182 time series collected from the initial baseline phases of single-case designs by T. A. Matyas and K. M. Greenwood (1985). The 182 values of râ‚ were tested for significance against the values provided by the simulation. Analyses revealed that 42 (23.1%) time series showed statistically significant autocorrelation; 32 were positive autocorrelations and 10 negative. Application of these findings, within the meta-analytic approach of B. E. Huitema, provided a convincing demonstration against his conclusion that autocorrelation in behavioral data is a myth.
