Ordinal+variables

The categories can be sorted. The numbers assigned to the categories mean something

Examples: Professor, Associate Professor, Assistant Professor, Instructor

The distance between the categories are not equal across the range

Example: Social Economic Status: 1=Upper class 2=Middle class 3=Working class 4=Lower class

Numbers in ordinal data are not real numbers in the sense that we cannot do math on them, we can only count and rank them

Nominal and ordinal data are often just called categorical variables
