30 Examples of Quantitative Variables

The quantitative variables are those variables whose alternatives represent quantities and, therefore, are expressed with numbers. For example: GDP, as it is expressed in numbers: $1.4 trillion.

Variables are the characteristics of a population that are analyzed in a statistical investigation and can acquire different values ​​(data that serve to record how a property changes from one element to another).

Quantitative variables differ from qualitative ones, because they acquire numerical values, that is, they are expressed in figures. For example: The income of a family, whose values ​​can be $28,754, $45,678, etc.

On the other hand, qualitative variables take non-numerical values, because they state attributes or qualities that are expressed in words. For example: The social class to which families belong according to their income level, whose values ​​are low class, middle class and upper class.
