In the same plant study, what is the dependent variable?

• A. Sunlight amount
• B. Plant height in centimeters
• C. Soil type
• D. Temperature

Answer: (B)

In experiments, the variable you measure to see how changing conditions affects the outcome is the dependent variable. In this plant study, you vary factors like sunlight, soil type, and temperature to see how they influence growth. The measurement you record as the result is plant height, usually in centimeters, which reflects how much the plant grows under those conditions. So plant height is the dependent variable. The other options describe conditions you control or categorize (sunlight amount, soil type, temperature), not the outcome you measure.
