If the height from which a ball is dropped affects how high it bounces, what is the dependent variable?

Back

The dependent variable is the height that the ball bounces.

Front

What is the purpose of identifying independent and dependent variables in an experiment?

Back

Identifying these variables helps to understand the cause-and-effect relationship in the experiment.
