The manipulated variable is the variable which researches change, while the measured variable is the variable that changes as a result of the manipulated variable.
Consider this simplified question: Do flowers grow better with more water?
Researchers plant flowers and put 10mL in one pot, 20mL in another, and 30mL in another. This is the manipulated variable.
Researchers measure how tall the flowers are. The height of the flowers is the measured variable, because it changes as a result of the amount of water added.

A manipulative variable is the variable you can alter, while the responding variable is the variable you have no control over. A manipulated variable is what is changed purposely throughout the experiment. The responding variable is which you have to measure to get your results I think. But the responding variable depends on the dependent variable. I believe I'm right!
the controlled variables are the factors that are kept constant during an experiment. if they are not kept constant then they may affect the outcome of the experiment. the manipulated variable is the factor that is different between the experiment and the control. the responding variable is the variable that is being measured in the experiment.

The independent variable is the value being manipulated or changed, while the dependent variable is the observed result of the independent variable being manipulated. "IF" you change the independent variable, "THEN" what happens to the dependent variable?
The difference between a variable resistor and a rheostat is the same as the difference between six and half a dozen.
