Numerical data

Types of numerical data

Numerical data can be further divided into two categories:

* continuous data - data that may take any value within a certain range.
This is generally data obtained by measurement. Examples: weight, time
spent waiting in a queue, temperature

* discrete data - data that may take one of a limited range of numbers.
Discrete data frequently use whole number values. Examples: number of
children in a family, time recorded to the nearest quarter of an hour,
number of runs scored by a cricket team
