Statistician's graveyard - commonsense!

Once a statistician reached to a river bank. Boats were ferrying people across the river. But the statistician observed that the bamboo stick with which the boats were pushed, were most of the time not deep enough in water! He requested the "fool" rowing the boat to measure the depth at various distances across the river. As per the statistician's expectations, the average depth of water was hardly coming up to the height of the waist of the statistician. So he decided to cross the river walking!
I know you all can guess where will the statistician go!
Rather where will he take all of us!
