Abstract:

In an experiment, only one variable (the independent variable) should be changed in an experiment. The dependent variable is dependent upon the independent variable and it is what is measured during the experiment. For example, we can measure the appearance of celery stalks (the dependent variable) when we place them in solutions of varying salt concentration (the independent variable).
