Why is it important to weight effect sizes by the number of participants in each study?
What will be an ideal response?
If you don’t do this, your average effect size across multiple studies is incorrect, because the effect size of each study would receive equal weight, regardless of the number of participants. This is especially damaging because small sample sizes are the most likely to have inaccurate results, and they will be given equal weighting in the overall effect size as larger studies whose data is likely more correct.
