Chapter 17, “Inferential Statistics”

This chapter focuses on inferential statistics, which are based on the laws of probability. It introduces sampling distributions, estimates of parameters, and levels of significance. In addition, the chapter provides an overview of some of the most commonly used inferential statistical tests, including t-tests, analysis of variance (ANOVA), and chi-square tests. Finally, the process of testing correlations is examined.

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

Review the information in your assigned chapter. As a group, develop a 1-page study sheet that includes the following: The key concepts of the chapter: Focus on the basic concepts that are important for nurses to understand as they review research studies. A description of the statistical methods covered in the chapter, what they measure, and under what circumstances they are used. Identify examples of how the statistical methods have been used in research studies. An explanation of the key statistical tests and how they measure significance (if applicable).

This is a group project, I'm only supposed to adress this 2 points.
