# Ch 9: Statistical Estimation

Watch video lessons to learn all about statistical estimation, including confidence intervals and t distribution. Test yourself after the lessons with interactive quizzes and a chapter exam.

## Statistical Estimation - Chapter Summary and Learning Objectives

Learn how to perform statistical estimations with the engaging video lessons in this chapter. As you work through this study guide, you'll learn the formulas for calculating and interpreting confidence intervals, the differences between biased and unbiased estimators and how to apply t distribution.

Lessons are short and focus on one concept at a time, so you won't have any trouble picking up new material. Each lesson also comes with a full video transcript that you can use to follow along or help you review. By the end of this chapter, you will be able to do the following:

• Differentiate between point and interval estimations
• Find the sample size and confidence intervals for sample means
• Understand and apply t distribution
• Find confidence intervals for proportions, matched pair means and independent sample means
