Ch 3: Measurement & Data in Chemistry

About This Chapter

This convenient overview of measurement and data in chemistry can quickly improve your understanding of the metric system, order of magnitude, and data analysis. These lessons were put together to help prepare you to take an exam or confidently engage in a class discussion.

Measurement & Data in Chemistry - Chapter Summary

In this chapter on measurement and data in chemistry, you can view engaging lessons that cover quantitative and qualitative data analysis. You can also review how to determine the quantity of orders of magnitude in numbers. After going through the lessons, you should be poised and able to do the following:

  • Explain how to perform calculations with measurements that limit uncertainty
  • Provide examples of order of magnitude
  • Discuss the metric system and how to convert units
  • List different techniques and methods of data analysis
  • Recall how to solve for unknowns in scientific equations

These fun and easy-to-comprehend lessons can help you easily grasp concepts related to measurement and data in chemistry. A short quiz is available to test your knowledge of each lesson, and the quizzes can be printed for offline review. You can also submit questions to our instructors if there are any topics you don't understand.

Measurements & Uncertainty in Science

1. 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.

Order of Magnitude: Definition & Examples

2. Order of Magnitude: Definition & Examples

In this lesson, you will learn the definition of order of magnitude and how it is closely associated with scientific notation. You will also learn how to determine the quantity of orders of magnitude in numbers with interesting real-life examples. Following the lesson will be a brief quiz.

The Metric System: Units and Conversion

3. The Metric System: Units and Conversion

Just like you and your friend communicate using the same language, scientists all over the world need to use the same language when reporting the measurements they make. This language is called the metric system. In this lesson we will cover the metric units for length, mass, volume, density and temperature, and also discuss how to convert among them.

Data Analysis: Techniques & Methods

4. Data Analysis: Techniques & Methods

In this lesson, we'll learn about data analysis. We'll define the two methods of data analysis, quantitative and qualitative, and look at each of their various techniques. The lesson will then conclude with a summary and a quiz.

Solve for Unknowns in Scientific Equations

5. Solve for Unknowns in Scientific Equations

Calculating a missing value in an equation is something you may come across in your scientific analyses. As long as you know the relationship between the variables in the equation, as well as the rest of the measured values, this is a relatively straightforward process for you to master.
