She hits 10 balls with the new bat, and then 10 balls with her old bat for comparison. She then measures the distance the balls go to see if the new bat’s claim is true.
What is the manipulated variable and responding variable for this experiment?
Manipulated Variable: Bat
Responding Variable: Distance ball traveled
