Urdan then delves into inferential statistics, beginning with probability and sampling distributions. He explains the importance of these concepts in making generalizations about a population based on a sample. The author also provides a detailed discussion on the central limit theorem, which forms the basis for many statistical analyses.

Next, Urdan introduces key inferential statistics, such as confidence intervals and hypothesis testing. He explains the process of setting up null and alternative hypotheses and the significance of p-values in determining the strength of evidence against the null hypothesis. The author also discusses the concept of effect size, which helps in understanding the practical significance of research findings.

Urdan then moves on to explore the various statistical tests, including t-tests, ANOVA, and regression analysis. He provides clear explanations of when and how to use these tests, and how to interpret their results. Throughout this section, he emphasizes the importance of understanding the assumptions and limitations of each test.
