○ Ordinal variable: A categorical variable where the categories have a natural ordering (e g age group, income level, educational status)
Variable Types
discrete (categorical) variables can be further classified into: ➢ nominal variable: no ordinal variable: there exist some ordering between categories (e g , size of automobile, some examples (from Agresti, 2002): p 2-6 NTHU STAT 5230

4 2 1 Categorical data The characteristics of interest for a categorical variable are simply the range of values and the frequency (or relative frequency) of occurrence for each value (For ordinal variables it is sometimes appropriate to treat them as quantitative vari-ables using the techniques in the second part of this section ) Therefore

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.
What are categorical variables?
Categorical variables are variables in the data set that unlike continuous variables take a finite set of values. For example, grades that students are given by a teacher for assignments (A, B, C, D, E, and F). Another example of a categorical variable is jersey color that a college is selling.
What is ordinal variable in statistics?
Ordinal variables are those variables which have discrete values but has some order involved. The variables do not have to necessarily directly correlate to a specific value, but is often used as a qualitative way of understanding data.
