This text on the design and analysis of clinical research studies, explains the basis of experimental design and statistics in a way that is sensitive to the clinical context in which nurses work. It uses data from actual studies to illustrate how to: design the study; use and select data; present research findings; and use a computer for statistical analysis. The scope of the study designs and associated statistical tecniques covered in the book allow both the beginning nurse researcher and the more seasoned professional nurse investigator to approach a research study with confidence and optimism. The authors show how qualitative data can be approached quantitatively, what the advantages of this are from the nursing viewpoint, and how quantitative methodology can help nurses to develop a common language with other disciplines invloved in patient care.
