Just in case you need these definitions

A manipulated variable the factor or quantity the investigator changes intentionally. This is established before doing the test.

A controlled variable is a factor that may alter or affect the results. You keep the value the same throughout the testing

Responding variable is factor or values that are measured results of the changed manipulated variable
