An independent variable in a scientific experimentation process is the one which can be changed or manipulated in a scientific experiment the effect of such a change can be observed on the dependent variable. The dependent variable is a variable which cannot be changed manually but the changes occur in the dependent variable are because of the independent variable. The changes that occur in the dependent variable are the outcomes of the experimentation process.

For example, the effect of the water and sunlight on the plant height can be used to explain the dependent and independent variables of the experiment. The dependent variable is the height of the plant which is dependent upon the independent variables such as water and sunlight.  

On the basis of the above explanation, One of the purposes of an experiment is to determine whether the dependent variable affects the independent variable is false.
