Educational Researcher, 35, 32— When effect sizes disagree: The case of r and d. Effect sizes[ and ] Central to literature meta-analysis is an understanding of effect sizes. The chief value of effect sizes in the literature of meta-analysis is that they provide a way to standardise effects across studies using different measures, allowing for common analysis.
There are many possible effect sizes, but essentially there are two commonly reported types in meta-analysis: Limitations[ meta ] An important limitation of meta-analysis is that and reviews can only be as good as the original data is valid. Meta-analysis can only analyse the role of independent variables in explaining variance in dependent variables if meta data is provided in the original studies.
