The independent variable is called what?

• A. The dependent variable.
• B. The confounding variable.
• C. The control variable.
• D. The independent variable.

Answer: (D)

In experiments, you focus on the factor you deliberately change to see how it affects the outcome. This is the independent variable—the element you manipulate to observe its effect on what you measure. The thing you measure is the dependent variable, which reflects the result of manipulating the independent variable. You also try to hold other variables constant (control variables) so they don’t influence the outcome, and you want to avoid or account for confounding variables—things that could also affect the result if not controlled. For example, if you’re testing how hours of study influence test scores, the hours of study are the independent variable, the test score is the dependent variable, keeping the testing environment consistent is a control variable, and factors like sleep quality or motivation could be confounding variables if not addressed.
