Chapter 2 Introduction to Quantitative Research Learning Outcomes After completing this chapter, you should be able to : 1.Define terms relevant to the quantitative research process—basic research, applied research, rigor, and control. 2.Compare and contrast the problem-solving process, nursing process, and research process. 3.Identify the steps of the quantitative research process in descriptive, correlational, quasi-experimental, and experimental published studies. 4. Read quantitative research reports. 5. Conduct initial critical appraisals of quantitative research reports.

Frequently, the idea of experimentation or study comes to mind. Typical features of an experiment include

randomizing subjects into groups, collecting data, and conducting statistical analyses. You may think of researchers conducting a study to determine the effectiveness of an intervention, such as determining the effectiveness of a walking exercise program on body mass index (BMI) of patients with type 2 diabetes. These ideas are associated with quantitative research. Quantitative research includes specific steps that are detailed in research reports. Reading and critically appraising quantitative studies require learning new terms, understanding the steps of the quantitative research process, and applying a variety of analytical skills. This chapter provides an introduction to quantitative research to help develop expertise in reading and understanding quantitative research reports. Relevant terms are defined, and the problem-solving and nursing processes are presented to provide a background for understanding the quantitative research process. The steps of the quantitative research process are introduced, and a descriptive correlational study is presented as an example to promote understanding of the process. Also included are a discussion of the critical thinking skills needed for reading research reports and guidelines for conducting an initial critical appraisal of these quantitative research reports. The chapter concludes
