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
-Scientific Hypothesis: A specific and testable prediction about the results of an experiment.
-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.
