View source for Dependent and independent variables

This article compares dependent variables, independent variables, and other [[Variable|variables]].

== Description ==

Variables used in an [[experiment]] or [[model]] can be divided into three types:

* '''Dependent variable'''
* '''Independent variable'''
* '''Other'''

The "dependent variable" represents the output or effect, or is tested to see if it is the effect.

The "independent variables" represent the inputs or causes, or are tested to see if they are the cause. 

Other variables may also be observed for various reasons.
