Ch 13: CBEST Math: Graphical Relationships

About This Chapter

Let us help you brush up on your graphical relationship skills. The video lessons and self-assessment quizzes in this chapter provide several approaches to help you succeed on the math portion of the California Basic Educational Skills Test.

CBEST Math: Graphical Relationships Chapter Summary

Do you know the difference between categorical and quantitative data? Can you construct a table to show how numerical information pertains to two different categories? If not, you might want to refresh your knowledge of graphical relationships before taking the California Basic Educational Skills Test (CBEST). In addition to addressing categorical and quantitative data and two-way tables, video lessons in this chapter cover the following topics:

  • Understanding bar graphs and pie charts
  • Summarizing categorical data using tables
  • Calculating percent increase with relative and cumulative frequency tables
  • Making estimates and predictions from categorical data
  • Creating and interpreting histograms
  • Reading and interpreting line graphs

Objectives of the CBEST Math: Graphical Relationships Chapter

The California Basic Educational Skills Test measures prospective public school teachers' proficiency in reading, writing and mathematics. This test is used as part of the credentialing process in both California and Oregon. Test takers are given four hours to complete the CBEST. The math portion of the exam includes 50 multiple-choice questions, approximately 35% of which gauge your skill in numerical and graphical relationships. Most of the test is presented as word problems.

This chapter on graphical relationships features a number of video presentations and self-assessments. The assessments can be used to test your knowledge of graphical relationships both before and after viewing the videos.

Statistical Analysis with Categorical Data

1. Statistical Analysis with Categorical Data

Learn why percentages are so important when analyzing categorical data in this video lesson. Watch as the data is turned into a data table and a visual bar graph as ways to analyze the data.

Understanding Bar Graphs and Pie Charts

2. Understanding Bar Graphs and Pie Charts

In this lesson, we will examine two of the most widely used types of graphs: bar graphs and pie charts. These two graphs can provide the reader with a comparison of the different data that is displayed.

How to Calculate Percent Increase with Relative & Cumulative Frequency Tables

3. How to Calculate Percent Increase with Relative & Cumulative Frequency Tables

In statistics, one way to describe and analyze data is by using frequency tables. This lesson will discuss relative and cumulative frequencies and how to calculate percent increase using these two methods.

What is a Two-Way Table?

4. What is a Two-Way Table?

Do you believe in Martians? Do you watch football on television? A Two-Way Table or Contingency Table is a great way to show the results of all kinds of survey questions. In this video we will learn how to read a two-way table.
