Answer 1

dependent variable

Answer 2

oh my gosh thank you but why is that?

Answer 3

Controlled variable - A variable that stays constant throughout the experiment, so as to eliminate any influence on the results.

Experimental variable - A variable that is changed in the experiment, so the effect can be studied.

Independent variable - A variable that you control the value of. It is controlled by the experimenter and so not dependent on the value of other variables.

Dependent variable - A variable that changes as a result of another changed variable, i.e. it is dependent on the other variable.

Answer 4

In an experiment, you change the experimental variable, which is also the independent variable, and measure the dependent variable(s), so see the effect. The controlled variables are, in a sense, also independent variables, but you eliminate their influence by keeping them constant, so they have no effect on the dependent variable you're studying.
