Which variable changes in response to the manipulated variable?

Which variable changes in response to the manipulated variable?

• A. Independent Variable
• B. Dependent Variable
• C. Control
• D. Solvent

Answer: (B)

The idea being tested is how a response variable changes when you deliberately alter another variable. The variable you change on purpose is the manipulated (independent) variable, and the one that changes as a result is the dependent variable. This question asks which variable changes in response to what you manipulate, so the dependent variable is the correct choice because it reflects the outcome you measure after the manipulation. For example, if you vary the amount of sunlight (manipulated variable) and watch how tall the plant grows (dependent variable), the growth changes in response to the sunlight level. The manipulated variable is not the one that changes in response, the control is kept constant for fair comparison, and a solvent isn’t the general type of variable being discussed here.
