Means, Standard Deviations, and Sample Sizes
Note: This method is the same as the method for means and standard deviations, except it uses standard errors of the means instead of standard deviations. The standard errors are converted to standard deviations, and then the canonical form of Cohen’s d and Hedges’ g are computed.
