Activity: Understand Data
This activity involves taking a closer look at the data available for mining. This step is critical in avoiding unexpected problems during the next activity—data preparation—which is typically the longest part of a project. Data understanding involves accessing the data and exploring it. This enables you to determine the quality of the data and describe the results of these steps in the project documentation.
