Answer to Question 1

A

Answer to Question 2

D
Feedback:
One strategy for exploring moderating effects on effect size is to do subgroup analyses, which involve splitting effect size information into distinct categorical groupsfor example, men and women. Effects for studies with all-male (or predominantly male) samples could be compared to those for studies with all or predominantly female samples. Subgroup analyses are not performed to ascertain heterogeneity, to address publication bias, or to determine the effects of exclusion criteria.
