What is a manipulated variable, controlled variable and a responding variable?

Definitions: Manipulated Variable- Also known as Independent Variable, This is what the scientist purposely changes Controlled Variable- Variable that stays the same Responding Variable- Variable that May (usually) or may not change. I hope you understand the definitions! Later, Kenya P.S. We just did this in science class, so it is fresh on my brain.

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

a manipulated variable is the variable that changes. the controlled variable is what you use to change the manipulated variable. the responding variable is i don't know.
