Being told to write "in AMA Style" can have more than one meaning. Carefully read your assignment or speak with the faculty who assigned it to determine what they want.
Case 1: "Write in AMA Style" is a reference style. This means that the references within the text and the bibliography at the end of the text should follow the guidelines laid out by the AMA Manual of Style. This is frequently used for papers and other writing in classes, and presentations conducted during classes or practice rotations. This guide includes detailed help on creating references in AMA Style.
Case 2: "Write in AMA Style" as a manuscript style. This means using proper references within the text and bibliography, but also using the stylistic matters laid out in the AMA Manual of Style to format the text. This includes such factors as using headings and capitalizing them appropriately, line spacing, margins, text style issues (such as using "one" or "1", using AM or a.m. or A.M.), placement of page numbers, preferred font and spacing for graphs, preferred size and shape for tables, etc. This is more frequently called for when publishing writing, submitting to a journal for peer review, or writing materials for presentation or distribution at professional meetings. This guide includes very little help on manuscript style, as it comprises about 500 pages of the Manual and is difficult to summarize. Consult the AMA Manual of Style for detailed information on manuscript style.
