Detailed explanation-1: -Ms. S set up an experiment to see how the mass of a ball affects the distance it rolls off a ramp. What is the dependent variable? Distance traveled by the ball.

Detailed explanation-3: -The dependent variable is the variable that is being measured or tested in an experiment. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores since that is what is being measured.
