Height that the ball bounces

Height from which the ball is dropped

Detailed explanation-1: -The height at which the ball bounces is the variable that is being determined and relies upon the height from which the ball is dropped, that is, the independent variable. Hence, the control variable would be the ball used.
Detailed explanation-2: -Because we can drop the ball from any height we choose, the drop height is called the independent variable. But since the rebound height depends on the drop height, the rebound height is called the dependent variable.
Detailed explanation-3: -We say that bounce height is the dependent variable and drop height is the independent variable.
Detailed explanation-4: -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.
Detailed explanation-5: -A controlled experiment is an experiment where only one variable is changed at a time, all other variables are kept unchanged.
