Ch 35: TACHS: Graphical Representations of Data

About This Chapter

Before taking the TACHS examination, your student could review graphical representations of data by watching the videos offered in this chapter. The lessons are about ten minutes in length, and they include quizzes that test comprehension.

TACHS: Graphical Representations of Data - Chapter Summary

This chapter could play a role in ensuring that your child understands the data represented in tables, schedules and graphs. By watching several video lessons, your eighth-grade student can recognize and tell the difference between numerical and categorical data. In addition to discovering the applications of line graphs, they could become proficient at using bar graphs prior to sitting for the TACHS examination. While studying these lessons, your eighth-grade student could receive assistance with:

  • Understanding the ways in which data can be organized
  • Exploring the use of tables and graphs in real life
  • Interpreting and creating line graphs, stem and leaf displays, and pie charts
  • Identifying the parts of a bar graph
  • Constructing histograms, dot plots and box plots

Led by professional teachers and filled with animation and graphics, these video lessons can be watched online via a tablet, laptop or other Internet-connected technology. The videos can be paused or stopped while your student works through examples that strengthen their knowledge. Expert support is provided interactively in case students have questions related to the topics above. Transcripts, quizzes and additional course information are included in the chapter.

TACHS: Graphical Representations of Data Chapter Objectives

Your child's reading, language, mathematics and reasoning abilities will be evaluated during the paper-based TACHS examination. The topics in this chapter could be encountered when they reach the mathematics section of this paper-based test.

When going to the November testing appointment, your student will need the Admit Card, some No. 2 pencils and his or her student identification card. Expect the testing session to last about two hours without breaks.

Organizing and Understanding Data with Tables & Schedules

1. Organizing and Understanding Data with Tables & Schedules

In math, when we have to deal with a lot of data, having a visual format to present all the data becomes very useful. Watch this video lesson to learn how you can take advantage of two of these visual formats.

Using Tables and Graphs in the Real World

2. Using Tables and Graphs in the Real World

We use tables and graphs in algebra as ways to visually show an equation or function. But do we really use these in the real world? Is it that important to learn about tables and graphs? Find out in this video lesson.

Reading and Interpreting Line Graphs

3. 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.

Creating & Reading Stem & Leaf Displays

4. Creating & Reading Stem & Leaf Displays

Every once in a while you will come across stem-and-leaf displays in statistics. These displays can be very useful in identifying all of the values in a data set while still visually representing the data.

Understanding Bar Graphs and Pie Charts

5. 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.

Creating & Interpreting Scatterplots: Process & Examples

6. Creating & Interpreting Scatterplots: Process & Examples

Scatterplots are a great visual representation of two sets of data. In this lesson, you will learn how to interpret bivariate data to create scatterplots and understand the relationship between the two variables.

Creating & Interpreting Histograms: Process & Examples

7. Creating & Interpreting Histograms: Process & Examples

Creating histograms can help you easily identify and interpret data. This lesson will give you several examples to better understand histograms and how to create them.

Creating & Interpreting Dot Plots: Process & Examples

8. Creating & Interpreting Dot Plots: Process & Examples

Dot plots are a visual way to display the frequency distribution in a data set. In this lesson, you will learn how to construct a dot plot and understand its uses.

Creating & Interpreting Box Plots: Process & Examples

9. Creating & Interpreting Box Plots: Process & Examples

Box plots are an essential tool in statistical analysis. This lesson will help you create a box plot and understand its meaning. When you are finished, test your understanding with a short quiz!
