The dependent variable causes a change in (the) a. independent variable (x) b. scores (x) c. hypothesis d. none of the these

Hypothesis shows the relationship between two variables that can be tested. It is called "cause-effect" relationship. The cause is independent variable and the effect is dependent variable. The change in the independent variable has an effect in the dependent variable and vice-versa is not correct. The scores are dependent variables itself. Something might cause to change it, not the dependent variable. To sum up, if there is a change in the dependent variable, it causes a change in the hypothesis.
