Reporting meta analysis
While the standards of how to report something in a publication vary widely by field and venue, the variation of what is expected in a class assignment is vastly larger - too large for really anyone outside of your class to say. 

If this were for publication, I would suggest you find papers in your field and from the publication source you are targeting to help guide you in how to structure reporting your findings. For an assignment, the only standard that will have much of any sway is what your instructor expects or requires - so I would highly recommend you review the assignment guidelines and syllabus, and then contact the instructor to request guidance on how to structure and summarize your findings, including what details they want included.
