Marking Observations

Marking by Nominal Variable

You can assign markers automatically based on the value of a nominal variable. This is a good way to distinguish quickly between groups of observations.

Select SEX in the data window.

Click on the multiple markers button at the bottom of the markers window.

SAS/INSIGHT software assigns a different marker for each value of the nominal variable. In this case, observations with a value of MALE are displayed with crosses, and observations with a value of FEMALE are displayed with squares.
