An '''independent variable''' is that [[variable]] presumed to affect or determine a [[dependent variable]]. It can be changed as required, and its values do not represent a problem requiring explanation in an analysis, but are taken simply as given.

An '''independent variable''' is that [[variable]] presumed to affect or determine a [[dependent variable]]. It can be changed as required, and its value.
 
Depending on the context, independent variables are also known as '''predictor variables''', '''regressors''', '''controlled variables''', '''manipulated variables''', or '''explanatory variables'''.
 
   
 
More generally, the independent variable is the thing that someone actively controls/changes; while the dependent variable is the thing that changes as a result. Thus independent variables act as catalysts for dependent variables. In other words, the independent variable is the "presumed cause", while dependent variable is the "presumed effect" of the independent variable.
