This section presents a series of case studies that demonstrate
the application of EDA methods to specific problems. In some cases,
we have focused on just one EDA technique that uncovers virtually
all there is to know about the data. For other case studies, we
need several EDA techniques, the selection of which is dictated by
the outcome of the previous step in the analaysis sequence. Note
in these case studies how the flow of the analysis is motivated by
the focus on underlying assumptions and general EDA principles.
