Manipulated and Responding Variables

Manipulated and Responding Variables

by Derek Atlas

​Variable: Any condition or factor that is able to be changed... able to vary

​There are 3 types of Variables we will investigate:

​1. Manipulated

​2. Responding

​3. Controlled

​Manipulated Variable:

Any condition or factor that is intentionally changed by the scientist

​Responding Variable: Any condition or factor that only changes in response to changes in the manipulated variable or as a result of changes to the manipulated variable.

​Controlled Variable: Any condition or factor that is kept the same throughout the experiment. In order to control it, it must be fully described in the procedure or materials.
