All of the above are required. In order to conduct a valid experiment, it is necessary to have an independent variable (the variable being manipulated), a dependent variable (the variable being measured), and an experimental manipulation (the change being made to the independent variable in order to observe its effect on the dependent variable). Only having one or two of these components would not constitute a true experiment.
