Question

Quizplus · Accepted Answer

The dependent variable is the variable that is being measured and is expected to change in response to the independent variable. In this case, the independent variable is nitrogen concentration, and the variable being measured is the productivity of Eucalyptus seedlings. Therefore, the dependent variable is Eucalyptus productivity. The other options are not relevant as they are not being manipulated or measured in this experiment.
