I want to develop an understanding for conducting Meta-Analysis studies in Psychology. how many studies to select, how to screen them, any tools which are used for the purpose. kindly explain with references how to conduct a meta-analysis
You need to develop a PICOS, then develop a comprehensive search string according to the PICOS, search databases, and screening articles as per the inclusion and exclusion criteria. perform data extraction, analysis, and evidence synthesis. manuscript writing.
It is a long process. I think one should learn before embarking on starting a new project.
Kindly refer my articles for conducting meta analysis.
I have collected articles in ten electronic databases - Springer, Elsevier, taylor and francis..etc., and used PRISMA guidelines.
refer this article
