External validity exists when the relationship experimental between the independent and dependent variables during the experiment is normal to the real world.
Laboratory experiments are example of internal validity. In these experiments the variables are dependent to each other and there exists a cause-effect relationship. In these experiments each and every variable is controlled and can be manipulated as per the requirement.
