For this project, you will use AMA style for your references (unless you get permission from your professor to use a different style).
AMA style uses superscript numbers for in-text citations and a reference list at the end of your paper. See the Purdue Online Writing Lab guide to AMA style or the official AMA Manual of Style for examples.
Consider using a citation management tool to help with your citations. These tools help you organize your sources and format your references. Both Zotero and EndNote have plugins for Word, which allow you to pull in citations as you write. Zotero also has a plugin for Google Docs.
If you don't already have a tool that you like, check out the comparison between Zotero and EndNote on the library's Citing Sources guide.
