Which variable is measured or observed as a result of the manipulated variable?

• A. Dependent variable
• B. Control
• C. Hypothesis
• D. Independent variable

Answer: (A)

In an experiment, you deliberately change one condition (the independent variable) to see how it affects another factor you observe and measure (the dependent variable). The question asks which variable is observed as a result of the change you made, so the dependent variable is the one you measure in response to the manipulated variable. For example, if you change the amount of sunlight the plant gets (independent variable), you would measure the plant’s growth (dependent variable) to see the effect. The control is kept constant for fair comparison, and the hypothesis is your prediction about the relationship.
