Chapter Outline

1.1 What Is Data Science?
1.2 Data Science in Practice
1.3 Data and Datasets
1.4 Using Technology for Data Science
1.5 Data Science with Python

Many of us use the terms “data” and “data science,” but not necessarily with a lot of precision. This chapter will define data science terminology and apply the terms in multiple fields. The chapter will also briefly introduce the types of technology (such as statistical software, spreadsheets, and programming languages) that data scientists use to perform their work and will then take a deeper dive into the use of Python for data analysis. The chapter should help you build a technical foundation so that you can practice the more advanced data science concepts covered in future chapters.
