The operational definition of a variable is the specific way in which it is measured in that study. Another study might measure the same conceptual measure differently. If you were studying ways of helping people stop smoking, smoking cessation would be an outcome measure (dependent variable).
Control variables - These are the same for each experiment. 2. Manipulated variables - are not the same only one thing is changed. 3. And the one you want responding variable - is the variable you are testing, you do not have control over it, its the outcome.
