5. dependent variable

6. dependent variable
(in an experiment) the event studied and  expected to change when the  independent variable is changed.
what you measure in the experiment and what is affected during the experiment. It is called dependent because it "depends" on the independent variable. In a scientific experiment, you cannot have a dependent variable without an independent variable.

8. independent variable
(in an experiment) a variable that is intentionally changed to observe its  effect on the dependent variable.
