What is the difference between ordinal and categorical?
- Ordinal.An ordinal variable is similar to a categorical variable. The difference between the two is that there is a clear ordering of the variables. Even though we can order these from lowest to highest, the spacing between the values may not be the same across the levels of the variables.
