The best way to avoid plagiarism is to cite the sources of the information you include in your document. In other words, you need tell the reader of your paper where you obtained the information. This applies to things you read (books, articles, web documents, pamphlets), see (videos or DVDs, online videos, television programs, charts/graphs, illustrations, photos or other images), hear (radio programs, lectures) - basically, anything that is not your own idea and is not common knowledge.
The Library has a very detailed online guide to APA style to help you cite your sources accurately.
SFU's APA Citation Guide for Business Sources includes examples of citations for annual reports and statistics.
For examples of citations in the list of Works Cited for books, articles, videos/DVDs, websites and more, see the Library's online MLA Guide and the MLA Style Guide (PDF).
