Pre_goal - I can tell the difference among the definitions of the dependent variable, independent variable, and the control variable.

Using the definitions below to answer questions #1-3.

Key Terms

-Variable: An element, feature, or factor that can vary or change (i.e. ramp height, etc.)

-Dependent Variable: A variable whose value depends on another variable and is measured.

-Independent Variable: A value not dependent on another value but directly changed by an experimenter.

-Control Variable: A variable that is kept the same throughout an experiment.

*There can be many control variables but only one variable can be directly changed (independent)

and for simplicity one measured variable (dependent). All other variables must be controlled.

Which definition describes a control variable.

What the experimenter directly changes.

What the experimenter measures as a result of changing something else.

What the experimenter doesn't ever allow to change and doesn't ever allow to affect the other variables.
