Is age a categorical variable?
Categorical variables represent data types that can be divided into groups. Examples of categorical variables are race, gender, age group, and educational level.
Is age a continuous variable?

Is categorical age nominal or ordinal?
Age can be nominal or ordinal, depending on the type of question. For example, at what age do you collect nominal data, are you the firstborn, or what is your position in the family to collect ordinal data. Age becomes ordinal when there is some kind of order.

How are categorical variables defined?

- Counts the number of unique values in the data set.
- Calculates the difference between the number of unique values in the data set and the total number of values in the data set.

What variable is age?
There are basically 2 types of variables in statistics: Numerical variables: Numbers that should be treated in the way they are normally used in mathematics. For example, age and weight would be considered numeric variables, while phone number and zip code would not be considered numeric variables.
What variable is gender?
There are two types of categorical variables: nominal and ordinal. A nominal variable has no internal order in its categories. For example, gender is a categorical variable with two categories (male and female) with no internal ordering of the categories. An ordinal variable has a unique order.
