Dependent and independent variables

When studying the relationships between variables, it is sometimes observed that one variable has an influence on the other, but not the other way around. The variable being influenced is called the dependent variable (DV). On the other hand, the variable doing the influencing is called the independent variable (IV).

An example of this may be where an individual’s height is influenced by age. In this case, the height would be the dependent variable whereas age would be the independent variable.
