Watch entertaining and quick videos to learn about visual representations in statistics. Take quizzes after you view the videos to test your knowledge of the material. Close out your study of this topic with a chapter exam.

## Visual Representations in Statistics - Chapter Summary and Learning Objectives

Find out how visual representations are used to analyze data and see examples of histograms, box plots, bar graphs and pie charts. Our professional instructors lead you through lessons on bivariate data, conditional frequencies and frequency tables using animations and graphics to bring these concepts to life. You can easily find definitions for key terms with the handy lesson transcripts that come with each video or review a main point in a video by using the video tags we provide. These short and flexible lessons can help you:

• Learn how to use frequency tables
• Differentiate between relative and cumulative frequency tables
• Interpret different types of visual representations
• Use univariate data to make arguments
