What does "Unselected" mean within survey results?

Within your Engagement Survey results you might sometimes see the word "Unselected" when you apply a slice or filter (e.g., when you slice by department). This refers to all employees who were not specified as belonging to a particular group within this demographic. So for example, if you Slice By Department and see "Unselected", this refers to any employees who do not have a department on file.
