In experimental design, the variable you measure to assess the outcome is the

• A. Dependent Variable (DV)
• B. Independent Variable (IV)
• C. Hypothesis
• D. Cross-Population Generalizability

Answer: (A)

Focus on what you measure to see the result. The variable you measure to assess the outcome is the dependent variable. It’s the outcome that changes in response to what you do in the experiment. The thing you deliberately change to test its effect is the independent variable, so you’re looking at how variations in the IV influence the DV. For example, if you’re studying how caffeine affects reaction time, the caffeine dose is the independent variable and the reaction time you measure is the dependent variable. The hypothesis is just the predicted relationship between those variables, and cross-population generalizability concerns whether the findings apply beyond the specific group studied, not the observed outcome itself.
