Fig. 38. Distribution of Stature in a 



Population 



The first million men in the American draft for the World 

 War showed varying numbers in the different stature-groups 

 classed in one-inch intervals, as shown in this diagram. Any 

 large number of men taken from the population at random 

 would show a similar distribution as to stature.
