### Importing data into Mathematica

Mathematica provides a very rich data importing and exporting suite. The two commonly used functions to load data into a worksheet are `Import`

and `ReadList`

. In this section, we will use `Import`

To load our dataset, we need to tell Mathematica where to look for it. The structure of the code and data provided in the accompanying book's website follow the same pattern for every chapter. Under each chapter folder, there is a folder called `data`

. The folder `chapter2...`
