The dependent variable is the variable being measured or observed in an experiment. In this case, the subjects' driving ability is being measured to see the effects of alcohol consumption. The independent variable is the variable being manipulated in the experiment, which in this case is whether or not the subjects were given alcohol. Experimental control refers to the measures taken to ensure that the experiment remains fair and reliable, and experimental blind refers to the method of keeping the subjects unaware of which group they are in. Neither of these terms accurately describes the measurement of driving ability in this experiment.
