Writing Numbers

Writing With Numbers - American Press Institute is an enormously helpful web page with links to many sites. I especially like Robert Niles' on Statistics Writers Should Know. Niles also edits the University of California's Online Journalism Review, a place to find answers to your questions about writing content online. If you thought this post would tell you when to write 7 or seven, that's an issue about style, as in a fixed system of presentation such as these guides. My predilection runs toward the AP, MLA, and Chicago style books, unless I'm writing something that requires a specific format, such as the AMA for medicine or the APA for psychology (and many of the social sciences).
