An experiment is designed to test the relationship between the initial height of a basketball before it is dropped to the height of its rebound bounce. the height of the rebound bounce is measured using a scale positioned behind the ball. in the above experiment, which factor is the dependent variable? the type of ball used the height from which the ball is released the height to which the ball rebounds the type of floor surface used

In this case we are going  to establish a relation between

a) Initial height of a basketball before dropping

b) Height of ball's rebound bounce

If we look at these two variables it can be easily interpreted that the "Height of rebound bounce" depends on the "Initial height of the ball before dropping". The higher the "Initial height of the ball before dropping", the higher will be the "Height of rebound bounce"

Thus it can be said that the dependent variable is the "Height of rebound bounce"
