a. The denominator used in estimating the effect sizes.
Cohen's d uses the pooled standard deviation.
Hedges' correction uses the pooled standard deviation, plus a correction factor.
Glass's delta uses the sample standard deviation of the control group.
Expert Solution
Step 1
In this case, we need to check whether there is a significant difference between genders in self-reported math achievement measures.
