# Ch 26: Praxis Mathematics: Measurement

### About This Chapter

## Praxis Mathematics: Measurement - Chapter Summary

Prepare for measurement questions on the Praxis Mathematics exam by reviewing units used in the U.S. to quantify weight, length and volume. You can also study metric units, like grams, meters and liters, and learn how to do the following:

- Identify standard units of measure
- Perform basic operations with measurements
- Convert between standard and metric units
- Convert units in the metric system

This chapter's video lessons and transcripts include visual illustrations and tables that make it easy to compare the two systems of measurement or learn how to convert between them. If you favor a more hands-on approach to studying these topics, self-assessment quizzes are also included at the end of each lesson to help you confirm your understanding of the lesson material.

### Praxis Mathematics: Measurement Objectives

Lessons in this chapter can prepare you for Praxis Mathematics exam questions asking you to determine which units of measurement should be used to solve the problem you're presented with. Around three of the exam's 50 multiple-choice questions cover this measurement content domain. The remaining questions address such topics as algebra, number theory, discrete mathematics, calculus, geometry, trigonometry and data analysis.

Test scores on the Praxis Mathematics exam are used by many state education boards to assess the content area knowledge and qualifications of applicants for a teaching license. It lasts two hours total and is available in computer- and paper-based versions.

### 1. Standard Units of Measurement for Length, Weight, Time & Capacity

Watch this video lesson to learn how to recognize the various units of measurement for length, weight, time and volume. Learn to recognize both U.S. units and metric units.

### 2. How to Perform Basic Operations with Measurements

In this video lesson, you will learn how measurements are very much like variables when it comes to adding, subtracting, multiplying, and dividing them. You will also see examples of how they are done.

### 3. How to Convert Standard Units of Measure

The United States uses pounds, miles and Fahrenheit for measurements, but the rest of the world uses the metric system. This video lesson will help you to convert from one to the other easily, so you can understand kilometers and kilograms, too.

### 4. How to Convert Units in the Metric System

If you can make dinner, you can convert units in the metric system. It's that easy! In this lesson, you'll learn about the three key things you'll need to perform conversions.

### 5. Evaluating Data: Precision, Accuracy & Error

The data you present as a scientist need to be as accurate, precise and error-free as possible. In this lesson, we'll discuss what each of these terms means, as well as how error is introduced into measurements and other data collection.

### 6. Measurements & Uncertainty in Science

In this lesson, you will discover the importance of precision and accuracy in science while learning to make measurements. Also, you will understand how to perform calculations with measurements that conserve precision and limit uncertainty.
