Your research should include material from as many sources as possible including books; professional journals; internet sources; interviews and media sources. There aren’t a set number of references you should use for your paper, but a college level research paper typically uses at least 5 sources.
Footnotes are not required, but you must include citations and references. The citations and references must be written in proper American Psychological Association (APA) form. You must also include a title page and abstract written in proper APA format. This is not an APA experimental paper so do not include an introduction, methodfkts, results, and discussion sections.
