# Independent-variable meaning

An example of an independent variable is a temperature that stays constant during a science experiment.

*A*= π

*r*

^{2},

*r*is the independent variable, as its value determines the value of the area (

*A*).

The definition of an independent variable is a factor that does not change in value based on other factors.

An example of an independent variable is a temperature that stays constant during a science experiment.

In mathematics, a variable whose value determines the value of other variables. For example, in the formula for the area of a circle, *A* = π *r*^{2} , *r* is the independent variable, as its value determines the value of the area ( *A* ).
