Identify the key components of an experiment: independent variable, dependent variable, control group, and any uncontrolled variables.
Understand that the independent variable is the one that is manipulated or changed by the researcher to observe its effect on the dependent variable.
Recognize that the dependent variable is the outcome or effect that is measured in the experiment.
In the context of this experiment, determine what is being manipulated by the researcher. Here, alcohol consumption is the variable that is being changed to observe its effect on driving ability.
Conclude that alcohol consumption is the independent variable because it is the factor being manipulated to study its impact on driving ability, which would be the dependent variable.
