Cohen's d uses the standard deviation rather than the standard error to remove the adjustment for the influence of sample size in its formula. Standard deviation is a measure of the variability within a sample, while standard error is a measure of the variability across samples. By using standard deviation, Cohen's d provides a standardized effect size that can be compared across different sample sizes.
