About This Chapter
Scientific Data & Calculations - Chapter Summary
Use this chapter's lessons to refresh your knowledge of reading scientific charts and graphs, and practice interpreting tables of scientific data. Our instructors describe how to use scientific notation, and you'll explore the metric system. You'll also study various calculations that help in analyzing and comparing scientific data. By the end of this chapter, you should be prepared to:
- Understand scientific graphs and charts
- Interpret tables of scientific data
- Define significant figures and scientific notation
- Work with the metric system
- Differentiate between descriptive and inferential statistics, and give examples
- Calculate median, mean, mode and range
- Examine range, variance and standard deviation
Our instructors, all professionals in the field, have created brief, enjoyable lessons that use plenty of examples and practice problems to help you get information. You can assess your knowledge with the quizzes that follow each lesson. The video tags in the lessons make it simple to go back to find a key passage that you want to review.
1. 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.
2. 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.
3. 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.
4. 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.
5. Descriptive & Inferential Statistics: Definition, Differences & Examples
Descriptive and inferential statistics each give different insights into the nature of the data gathered. One alone cannot give the whole picture. Together, they provide a powerful tool for both description and prediction.
6. How to Calculate Mean, Median, Mode & Range
Measures of central tendency can provide valuable information about a set of data. In this lesson, explore how to calculate the mean, median, mode and range of any given data set.
7. Measures of Variability: Range, Variance & Standard Deviation
Looking specifically at range, variance, and standard deviation, this lesson explores the relationship between these measures and samples, populations, and what it says about your data.
