A Meta-analysis is the statistical analysis of results from numerous independent studies within the same research subject. Researchers can convert a range of study results into data points, and use them to show patterns or phenomenon.
A meta-analysis will include:
1. A research question
2. A set of representative studies that have been reviewed and coded for important information
4. A systematic analysis of the data
5. A set of conclusions that can be used to guide future research
