Ch 9: Sampling Distributions in Statistics

Use our video lessons and quizzes to learn about sampling distributions. Each lesson breaks down a concept into bite-sized pieces to help you understand the essentials of sampling distributions.

Sampling Distributions in Statistics - Chapter Summary and Learning Objectives

The short lessons in this chapter teach you all the methods for finding and using probabilities, including the steps needed to find z-scores, estimate population percentages and use normal distribution. Lessons use graphics and animations to make it easier for you to understand these concepts and entertain you in the process. You'll find plenty of examples and opportunities to practice the skills you're learning in these fast videos that take about 5-6 minutes to watch. By the end of the chapter, you'll be familiar with:

• The characteristics of normal distribution
• Methods for estimating areas under the normal curve
• Uses for the law of large numbers
• Ways to find mean and standard error of a sampling distribution
