In Chapter 1 we were introduced to the six data mining tasks:
In the description task, analysts try to find ways to describe patterns and trends lying within the data. Descriptions of patterns and trends often suggest possible explanations for such patterns and trends, as well as possible recommendations for policy changes. This description task can be accomplished capably with exploratory data analysis (EDA), as we saw in Chapter 3. The description task may also be performed using descriptive statistics, such as the sample proportion or the regression equation, which we learn about in Chapters 4 and 5. Table 4.1 provides an outline of where in this book we learn about each of the data mining tasks.
