Match the following terms to the correct definitions:

Draggable itemarrow_right_altCorresponding Item

Dependent Variable

arrow_right_alt

The variable which is manipulated or changed during the experiment

Controlled Variable

arrow_right_alt

The variable that is the actual measured or observed outcome of the testing. What happens to this variable DEPENDS on how the independent variable is changed or manipulated.

Independent Variable

arrow_right_alt

All other variables that must remain the same during the experiment and/or testing in order to validate the independent variable.
