## Inferential Statistics - Chapter Summary and Learning Objectives

The lessons in this chapter, taught by an expert instructor, will show you what inferential statistics are and how they are used in psychology research. You'll learn about hypothesis testing and the levels of statistical significance. Other lessons describe different types of tests and their purposes. You'll also learn about the analysis of variance, called ANOVA, and its function in comparing multiple groups. This chapter can help you understand the following:

• Definition of inferential statistics
• Comparing the null and alternative hypothesis
• Definition of statistical significance and levels of significance
• What are one- and two-tailed tests?
• Definition of chi-squared tests and t-tests
• ANOVA and how it is used

Video Objective
Inferential Statistics for Psychology Studies Define inferential statistics and discuss their uses in the field of research psychology.
Hypothesis Testing: Comparing the Null and Alternative Hypothesis Explain the process of hypothesis testing by comparing the null to the alternative hypothesis.
Statistical Significance: Definition, Levels and Critical Regions Define statistical significance. Discuss the various levels of significance, such as type 1 and type 2 errors, and critical regions.
One-Tailed vs. Two-Tailed Tests Differentiate between one-tailed (directional hypothesis) and two-tailed (non-directional hypothesis) tests for statistical significance.
What is a Chi-Squared Test? - Definition and Example Define and discuss the chi-squared test as a statistical hypothesis test.
What are t-Tests? - Assessing Statistical Differences between Groups Define and discuss the t-test as a means of assessing if two groups are statistically different from each other.
