Interval Estimation of Standardized Mean Differences in Paired-Samples Designs
Bonett, Douglas G.
Journal of Educational and Behavioral Statistics, v40 n4 p366-376 Aug 2015
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.
