Quizplus · Accepted Answer

The dependent variable is the variable that is being measured and tested in the experiment. In this case, the researcher is testing whether talking to plants enhances their growth, so the dependent variable is plant growth. The independent variables are the variables that are being manipulated by the researcher, in this case, whether or not the plants are being talked to. The other variables, food, water, and sunlight, are controlled variables, meaning they are kept constant throughout the experiment, so they are not the dependent or independent variables.
