About This Chapter
Scientific Data Collection & Analysis - Chapter Summary
The entertaining lessons in this chapter can help you brush up on gathering and interpreting scientific data. Watch these lessons to learn about tools and methods that scientists use to collect and measure evidence when working on specific problems, as well as how they summarize their findings and check their data for errors. Specific topics you will learn about include:
- Standard units of measurement
- Significant figures and scientific notation
- How to evaluate data
- The definition and uses of descriptive statistics
- Reading and interpreting scientific graphs, tables and charts
Our lesson instructors share their extensive expertise with you on these subjects in a convenient online format. When you complete a specific lesson, you can then answer the questions in that lesson's practice quiz to see how much you have understood about that topic. When you complete all of the lessons, test your understanding of the overall subject by taking the final chapter exam.

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. Significant Figures and Scientific Notation
Are 7.5 grams and 7.50 grams the same? How do scientists represent very large and very small quantities? Find out the answers to these questions in this video.
3. Evaluating Data: Precision, Accuracy & Error
The data you present as a scientist needs 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.
4. What Are Descriptive Statistics? - Definition and Uses
This lesson is a simple walk-through of the common types of descriptive statistics and why they are important for understanding psychological research. You will likely be familiar with many of them but some you may not be.
5. How to Read Scientific Graphs & Charts
How do scientists summarize their findings with visual aids? In this lesson, explore the different types of tables, charts and graphs that scientists use. Learn to read these effectively as a preview to your science studies.
6. Interpreting Tables of Scientific Data: Practice Problems
Complex table problems getting you down? Multi-question, situational problems don't have to be a drag on your testing performance. Learn how to apply three simple rules as we walk through two table problems together.
7. Interpreting Graphs and Charts of Scientific Data: Practice Problems
Do charts and graphs make problem-solving difficult? Complex problems with visual representations can drain your brain during a test. In this lesson, learn three simple rules for solving problems with charts and graphs. We'll try them out as we walk through two sample problems.
