In this Discussion, you examine different types of statistics and statistical tests, when and why these particular tests would be selected for use, and, most importantly, what the results indicate.

As a nurse engaged in evidence-based practice, it is important to recognize how statistics and other data analysis tools are used to generate and assess evidence. Most nurses need only a foundational understanding of statistical tools and terminology to understand the majority of research studies. As a nurse, you should be able to recognize the most commonly used statistical tests, how and when they are used, and how significance is determined.

In this Discussion, you examine different types of statistics and statistical tests, when and why these particular tests would be selected for use, and, most importantly, what the results indicate.

Chapter 23, “Qualitative Data Analysis”

The focus of this chapter is qualitative data analysis, which is more difficult in some ways than quantitative analysis, because there are not specific tests that can be used. Instead, much of the analysis is based on the researcher’s ability to identify patterns of behavior or similarities in events. Suggestions are provided for analysis of each of the major types of qualitative studies and how to document findings.
