Here we provide datasets used as examples and the more detailed worked examples. You can download the entire set of examples as a zip file here.

From the zip file, extract the files, and you’ll see the examples organised by chapter.  Alternatively, open data.html in your web browser. You’ll then be able to work through all of the examples.

For each data set, there is a small text file that explains the structure of the data files, then the data in Excel or csv format.
