What are manipulated variable and responding variable?

Answer 1

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

If you have a tank with a flow in and you have to control the level of the tank by changing the flow out, then the level is the controlled variable, since you are controlling it and the flow out is the manipulated variable since you manipulate it to get a result. There is a term for the flow in which you cannot change, but I forgot what it is.

Answer 2

the manipulated variable is the part of the experiment that is changed. the dependent variable is the part of the experiment that does not get changed(stays the same throughout the experiment), and the scientist use it to record the data.

Answer 3

The manipulating variable is the independent variable and the researcher controls and changes it during the experiment. The responding variable is the dependent variable and changes during the experiment, when the researcher alters the manipulating variable.
