Meta-analyses are crucial for synthesizing research findings in communication studies. They provide a comprehensive overview of existing evidence, helping researchers identify patterns and draw robust conclusions.
Reporting standards ensure and reproducibility in meta-analyses. By following guidelines like and , researchers can effectively communicate their methods, results, and limitations, allowing others to evaluate and build upon their work.
