Answer:
The independent variable is what is being changed intentionally by the researcher.
Explanation:
We often call the independent variable the manipulated variable, because it's what is being changed in the experiment. The dependent variable responds to the independent variable and is what is measured.
For example, if you want to determine how much water you should give a plant for maximum growth, the thing that is being changed intentionally would be the amount of water you are giving each plant, so that is the independent variable. The dependent variable is growth, so you might measure height of the plant or the number of leaves that grow. The growth is dependent upon the amount of water.
