No You need addtional information related to how much energy was dissipated during the contact with the floor. You can see this by considering a thought experiment: imagine dropping balls of different materials, but all from the same original height.
If we assume a perfectly elastic interaction, then the ball bounces back up to the original height. Some rubber balls get close to this. A "perfectly plastic" interaction dissipates the maximum possible energy and the rebound height is zero; think of dropping a lump of wet clay.
The effect is sometimes quanitifed by the notion of "coefficient of restitution"
