Abstract: Paired-samples designs are used frequently in educational and behavioral research. In applications where the response variable is quantitative, researchers are encouraged to supplement the results of a paired-samples t -test with a confidence interval (CI) for a mean difference or a standardized mean difference. Six CIs for standardized mean differences were examined and two were found to perform well under a wide range of conditions.
