    • Exploratory Data Analysis (EDA) is an approach/philosophy for data analysis that employs a variety of techniques (mostly graphical) to
      • 1. maximize insight into a data set;
      • 2. uncover underlying structure;
      • 3. extract important variables;
      • 4. detect outliers and anomalies;
      • 5. test underlying assumptions;
      • 6. develop parsimonious models; and
      • 7. determine optimal factor settings.
    • Focus: The EDA approach is precisely that--an approach--not a set of techniques, but an attitude/philosophy about how a data analysis should be carried out.
