Information
Meta-analysis is a research synthesis method that involves reviewing primary research on a specific topic to integrate findings. This process is crucial to the scientific enterprise as it allows for properly evaluating evidence for different hypotheses and formulating generalizations. Research synthesis can be conducted qualitatively through narrative reviews or quantitatively using statistical methods to integrate results from individual studies (Koricheva et al., 2013).
Meta-analysis has had a transformative effect in many scientific fields, leading the way in establishing evidence-based practice. More importantly, it has been instrumental in resolving seemingly contradictory research outcomes, showcasing its problem-solving capability and revolutionary impact.
Meta-analysis is more than just a technique; it is a well-regarded and favoured approach for combining research results across different fields. Based on current studies, it offers a comprehensive evaluation of a statistic's size, thereby strengthening its reliability and significance.
