Vocabulary

Independent Variable:  A variable (often denoted by x) whose variation does not depend on that of another.

Dependent Variable:  A variable (often denoted by y) whose value depends on that of another.

Research Question:  A research question is the question around which you center your research. It should be clear: it provides enough specifics that one's audience can easily understand its purpose without needing additional explanation.
