An Abstract is a short summary of an article. It is both informative and descriptive. Abstracts tell the reader what is in an article. They do not analyse or make conclusions. It must accurately state the contents. They tell the reader what is in a research article and encourage the reader to read the original article.
Research abstracts should include the objective and scope of the investigation, the methods used in the research, the primary results and the main conclusions as stated in the article.
