Numerical
variables/**quantitative**

The values of a
**numerical** variable are numbers. They can be
further classified into **discrete** and
**continuous** variables.

Discrete numerical variable

A variable whose values are **whole numbers**
(counts) is called discrete. For example, the number of items
bought by a customer in a supermarket is discrete.

Continuous numerical variable

A variable that may contain **any value within some
range** is called continuous. For example, the time that the
customer spends in the supermarket is continuous.

Categorical variables /
**qualitative**

The values of a
**categorical** variable are selected from a small
group of categories. Examples are gender (male or female) and
marital status (never married, married, divorced or widowed).
