It is called an independent variable. For example, you give some people Dark Chocolate and other no chocolate at all. You measure their well being. The amount of chocolate is something YOU control, so it is the independent variable. The well being depends on the chocolate. We would expect more dark chocolate would make much happier people. That would be the dependent variable.
