Research design is the plan, structure, and strategy of investigation for answering the research question. The correct design helps isolate items of concern so that they can be examined under known conditions; it eliminates bias and reduces the margin of error, enabling the researcher to state confidently conclusions on which to base future decisions and research. Regardless of the type of research proposed, following a logical plan, such as we have described here, provides the framework for an effective study. The results of well-planned research are contributions to the growing body of nursing knowledge.
