The APA style is a set of guidelines for scientific communication established by the American Psychological Association . The guidelines vary from describing the role of ethics in publishing to offering basic guidance on writing an article, and citing sources. All guidelines appear in the seventh edition of the Publication Manual of the American Psychological Association .
Students, teachers, researchers, and professionals in the fields of psychology, education, social work, nursing, business, and many other behavioral and social sciences should use the APA style rules included in the Publication Manual of the American Psychological Association.
Uniform style helps you identify easily key points and findings in a paper. It also assists you in presenting in an organized way the information you want to convey to your audience. Finally, it allows you to codify with accuracy and respect the elements required in order to give credit to those, who inspired your work.
The APA style follows the author-date system to describe the information sources cited in a paper. This means that the author and the publication date of the source are always provided in the citations. In this documentation style, each work should have a short in-text citation in the body of the paper and a corresponding detailed reference at the end of the paper.
