The measurement
level of a variable is a classification that describes the type of
data that a variable contains. Variables can be numeric or character
depending on their measurement levels. In
SAS/GRAPH Network Visualization
Workshop, the measurement level can be one of the following measurement
levels:
| Nominal |
Variables can be either numeric or character. |
| Interval |
Variables must be numeric. |
To change
the measurement level of a variable:
-
Select
the variable in the data table.
-
Right-click
and select either
Interval or
Nominal.
Your change
remains in effect only while the current project is open. If you close
and then reopen the project, then your change is not saved.
