In this article, the authors address the practicalities of how data should be presented, summarized, and interpreted. There are no exact rules; indeed there are valid concerns that exact rules may be inappropriate and too prescriptive. New procedures evolve, and new methods may be needed to deal with new types of data, just as people know that new ingredients may require modified cooking methods. However, most writers should follow reasonable principles based on current practice, although some flexibility is required, as the authors show in this article. (Contains 2 figures.)
