Answer:
independent variable; dependent variable
Explanation:
An independent variable, in a research study, is the variable that can be manipulated be the researcher, and brings about an effect on the dependent variable. It is referred to as “the cause”. The independent variable when manipulated, brings a change to the dependent variable. The dependent variable, on the other hand, is the effect of the cause of the independent variable. The effect is dependent on the manipulation of the cause.
