This section (Chapters 4 through 8) introduces the NodeXL tool for analyzing networks using a hands-on approach. It assumes no knowledge of network analysis tools and assumes only a basic familiarity with social network analysis concepts (see Chapter 3). The section has been used as the basis for workshops and classroom lab sessions and takes approximately 8 h to complete with participants following along, though abbreviated versions can also work. It also serves well as a walk-through of NodeXL, introducing all of the basic functionality. We recommend working through the examples using the datasets available at the book’s accompanying website: https://www.smrfoundation.org/nodexl/teaching-with-nodexl/teaching-resources/​. The examples found in the chapters in Part III assume you have read the Part II chapters.
