Different ways to set up data mappings

Grouping data using data mappings provides flexibility to set up data mappings that are customized to fit your needs. For example, consider a study in which a weight value is collected for every subject. To group all weight information, you have several options:

• If a single Weight item appears on multiple forms, you can add a Weight item to a Weight data series.
• If multiple Weight items appear in the study, you can:
  • Add all Weight items to a Weight data series.
  • Add one or several Weight items to multiple Weight data series.

If you create three data series (one for each value type), you have the ability to map a different value type to each data series. Consider using naming conventions to indicate the data series used for the different value types. For example, for Weight data series, you could create the following data series: Weight_Normalized, Weight_Entered, and Weight_Units.
