There are two kinds of variables. Independent variable and dependent variable.  

The factor which is different between the control and various experimental groups is known as the independent variable and it is known by the name of an independent variable because it does not depends on what happens in the experiment and this is something which a person conducting an experiment chooses to apply by himself or herself. The dependent variable is totally opposite to independent variable, It is an experiment which is a response to measure to see if the treatment had an effect or not. The dependent variable depends on the independent variable and not vice versa.
