Definition

Quantitative variable A variable measured on a numeric (i.e., interval or ratio) scale, such that each numerical value represents an amount A variable that is not quantitative is known as qualitative.

Examples

The following are examples of quantitative variables:

• Weight
• Height
• Population size
• Shoe size
• Average speed of racing cars

Note that coding a gender variable as 1=male and 2=female is not quantitative in nature as the numbers do not represent an amount.
