Answer:
The variable that changes in response to another variables is called Dependent Variable.
Explanation:
Doing quantitative research, we need to define and operate variables which are the center of the study. These are Independent and Dependent Variable.
A Independent Variable, as its name indicates, it's the one that doesn't depend on any other variable, like time, for example. This variable is the cause of a specific phenomenon.
A Dependent Variable is the opposite, it's the variable that's affected by the independent. This variable is the effect studied.
So, the relation between these two variable is crucial in every research, because their study is observed to prove or reject the hypothesis.
