Independent variable

From Wikiversity

An independent variable is used in statistics to predict or explain a dependent variable.

For example, Age and Gender might be used as independent variables to predict average age of death (a dependent variable).

In experimental designs, the independent variables are manipulated by the researcher (e.g., different dosages of a drug). In quasi-experimental and non-experimental designs, the independent variables may be naturally-occurring, non-manipulated variables which are measured and used to predict variations in the dependent variables.
