Meta-analysis: definition and general procedure.
Meta-analysis is the statistical integration of conceptually similar studies to produce a weighted average closer to the true value which all studies intend to achieve, albeit with a certain degree of error due to various factors. The Meta-analysis is an analysis and integration of studies aiming to produce high quality evidence to a question. The following are the general steps involved in all meta-analysis procedure.
A theory based question is formulated
scholarly works are searched for the framed questions in databases such as PubMed, Medline, Google Scholar, or any other valid source of scientific research.
The abstract and title of the individual papers are read and relevant ones are chosen.
Information from the selected final set of articles is extracted.
The hierarchy of scientific evidence or the evidence pyramid:
The scientific evidence pyramid is a visual representation of quality of evidence in scientific studies.
The base of the triangle is the long but it is weak in its quality. Similarly, the number of sources that form poor quality evidence is higher than other types of study. i.e., the number of sources is large like the base.
The quality of the evidence increases as we move towards the top of the pyramid, while, the number of sources decreases.
Just below the pinnacle is the systematic review. Systematic review is the collection and synthesis of high quality evidence to a particular question.
At the pinnacle is the meta-analyses which a statistical integration of quantitative results to provide an estimated value. In other words, it is the analysis of analyses.
Meta-analyses, together with systematic reviews form the highest quality of evidence in scientific studies.

STATISTICS WORK FLOW
Are you stuck in doing the Data Analysis in Research plan? Statswork guide students and researchers in designing their study, data analysis, and interpretation.
The outline of the research plan helps to identify why we are doing /conducting the study, how the study examines the research problem, why this research study is significant and recognize the research questions, which you are seeking to answer/examine in this particular research study. Planning of research is an intricate process, and it requires utmost care and diligence. It is important to give a clear and detailed attention when you plan for the research.
