Which term describes the data you measure in an experiment?

• A. Independent Variable
• B. Hypothesis
• C. Control Group
• D. Dependent Variable

Answer: (D)

Data you measure in an experiment are the results that show how a variable responds to what you change. This is the dependent variable—the outcome you record because it depends on the condition you manipulate. You systematically vary the independent variable and then collect measurements of the dependent variable to see the effect. For instance, if you change the amount of light a plant receives and measure how tall it grows, plant height is the data you gather, i.e., the dependent variable. The independent variable is the factor you deliberately change to test its effect. A hypothesis is a testable statement about what you expect to happen, and the control group provides a baseline for comparison but isn't the data you're collecting to assess the effect itself.
