Which term describes the variable that researchers measure to determine the effect of changing the independent variable?

• A. Independent variable
• B. Dependent variable
• C. Constraint
• D. Plantation

Answer: (B)

In experiments, the variable you measure to see the effect of changing something you control is the dependent variable. It depends on the independent variable, which you deliberately change to test its impact. For example, you might vary sunlight exposure and measure plant growth or biomass to see how light affects growth—the growth is the dependent variable. The independent variable is what you change, a constraint is just a limit or condition of the study, and plantation isn’t related to how variables are described in this context.
