**10 Steps to Write a Research Paper in APA Format**

APA format is the research paper style developed by the American Psychological Association. In college and graduate school, APA is the standard style for writing research papers that describe studies or experiments. Especially in psychology, sociology, and human health classes, professors often require students to write term papers in APA format.
