Data Understanding

Modeler has numerous resources for exploring your data in preparation for the other phases. We will demonstrate a number of these in Chapter 3, Importing Data into Modeler; Chapter 4, Data Quality and Exploration; and Chapter 8, Looking for Relationships Between Fields. The Data Understanding phase includes activities for getting familiar with the data as well as data collection and data quality. The four Data Understanding tasks are:

• Collect initial data
• Describe data
• Explore data
• Verify data quality
