Distribution Theory for Glass's Estimator of Effect size and Related Estimators

- L. Hedges
- Mathematics
- 1 June 1981

Glass's estimator of effect size, the sample mean difference divided by the sample standard deviation, is studied in the context of an explicit statistical model. The exact distribution of Glass's… Expand
