What is the average height for a white 17-year-old girl?

There is no such thing as adverage. Each person is unique, one of a kind. By this reasoning you as am I, are very special. There is a good book regarding adverage/normal. It is "Normal is a Setting on the Clothes Dryer i agree with the first answer but what i think is that a short 14 year old would be around 5'2 and a tall 14 year old would be around 6ft. so i guess the adverage is around 5'6.
