Feature Summary
What to Consider
- Plan the variables that will be Universal Subject Variables. These variables are used across all projects. Subjects enrolled in subsequent projects will not need their universal subject variables re-entered. Individual projects can opt out of viewing any of the Universal Subject Variables.
- A variable group that will be collected on multiple occurrences only needs to be created one time. The intervals determine the data collection schedule and the same variable group can be collected on multiple intervals.
- When creating a variable, be sure the variable type is correct. The variable type cannot be changed once data is collected. A common error is to use a text type variable instead of a numeric type variable.
