About This Chapter
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.
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.
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.
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.
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.
5. Summarizing Categorical Data using Tables
Watch this video lesson to find out why data tables are an excellent way to summarize your categorical data. Learn what you need to do to your data before constructing a table and the two ways you can show your data.
6. Make Estimates and Predictions from Categorical Data
Categorical data can be estimated but not predicted. Learn why in this video lesson along with how to read and gather information from a bar graph of categorical data.
7. What is Quantitative Data? - Definition & Examples
Watch this video lesson to find out the difference between saying you have seven apples and saying that those apples are delicious. You will learn about quantitative data and why it is useful.
8. What is a Histogram in Math? - Definition & Examples
Watch this video lesson to see how useful a histogram can be when you need to show a bunch of data in an easy to read format. Also, learn how you can easily gather the information you need from looking at a histogram.
9. Reading and Interpreting Line Graphs
Watch this video lesson to find out how useful line graphs can be and how much information you can gain just from looking at one. Learn how you can apply that information in your own life to help you make better decisions.
