Once again remember that references need to be in alphabetical order according to surname. In other words, what is it that you set out to investigate in your analysis or review. In applied research, it might describe a phenomenon or theory, then describe how that phenomenon or theory applies to some important real-world situation, and finally suggest a way to test whether it does, in fact, apply to that situation.
Does it have practical implications? Another would be to answer the main question first and then to answer secondary ones. Provide any conclusions or implications of the study. These style guidelines specify different aspects of a document's presentation and layout, including how pages are structured, the organization of references, and how citations are made.
For example, an abstract summarizing an experimental paper will differ from that of a meta-analysis or case study. In these cases as well, the abstract should include all of the major elements of your paper, including an introduction, hypothesis, methods, results, and discussion.
