Correlation Designs and Analyses

The clinical nurse specialist is frequently the person within the nursing department who leads nursing research studies. Because there are so many options available and these options are predicated on the research questions (Table 1) and the level of measurement, it is important that the clinical nurse specialist is aware of the options and criteria used to make the best option selections. Research designs are typically designated as qualitative or quantitative. The 4 major quantitative designs are classified as descriptive, correlation, quasi-experimental, and experimental. The purpose of this article is to provide important information needed to design, conduct, and analyze a correlation study.
