# Ch 25: Data, Statistics & Probability

Familiarize yourself with the uses of various charts, graphs and tables in time for the GED exam's mathematical reasoning section. Video lessons and quizzes can also show you how to calculate probability, permutations, combinations and measures of central tendency.

## Data, Statistics & Probability - Chapter Summary

Prepare for the GED exam's mathematical reasoning questions assessing your ability to read and interpret graphical representations of data. Lessons in this chapter can introduce you to the following:

• Tables and schedules
• Pie charts and bar graphs
• Line graphs and scatterplots
• Groups and frequencies on a histogram
• Combinations and permutations
• Mean, median, mode and range
• Independent and dependent event probability

Instructors teaching the data, statistics and probability chapter use real-life examples, graphics and sample problems to explain each concept. In addition to short, entertaining video lessons, content is available in the form of corresponding transcripts that include links to supplementary text lessons. This chapter also provides you with quizzes that can help ensure you understand each concept.

### Data, Statistics & Probability - Chapter Objectives

The GED exam is a 4-part test that includes a 90-minute mathematical reasoning section designed to assess your quantitative problem-solving skills through a series of multiple-choice, fill-in-the-blank, hot spot and matching questions. This chapter can help you prepare for questions that require you to use combinations and permutations to determine the number of event outcomes, calculate probabilities and extrapolate data from a variety of charts and graphs. Results on this and other parts of the exam are used to determine test takers' academic preparedness for a high school equivalency diploma.
