Literature reviews can be categorized as experimental and theoretical.
Experimental literature review basically refers to surveying all the information available on a particular topic and critically analyzing the gaps that need to be worked upon.
When you decide on a research topic, usually the first step you take in the direction of conducting research is learn more about the previous research published on the topic, and this eventually translates into literature review when you write your research paper.
Literature review is one of the pillars on which your research idea stands since it provides context, relevance, and background to the research problem you are exploring.
This statistical analysis is more accurately called meta-analysis, although this phrase has become interchangeable with systematic review" (pp.
204-205): A systematic review: A traditional or narrative review summarizes different primary studies from which conclusions may be drawn into a holistic interpretation supplemented by the author's own experience, theories, and/or models: Whereas a meta-analysis is a way of testing a hypothesis, a meta-synthesis attempts to integrate results from a number of different but inter-related qualitative studies.
The study therefore provides strengthened results that are validated by the scientific rigor of the analytical method.
Before starting to write a review, it is important to determine what kind of review you want to write and follow the appropriate style and guidelines.
In this sense, it essentially forms the first experiment of any research project.
The more extensive the review, the more precise and systematic the research project will be.
