The review of literature in quantitative research directs the development and implementation of a study. The focus of the major literature review at the beginning of the research process is to identify a gap in what is known. The study is designed to add knowledge in the area of the identified gap. After a thorough review of the literature, the researcher identifies a specific gap in knowledge. After the data have been analyzed and the findings described, the researcher will return to the literature in the generalization phase of the research report to integrate knowledge from the literature with new knowledge obtained from the study. The purpose of the literature review is similar for the different types of quantitative studies (descriptive, correlational, quasi-experimental, and experimental).
