The idea
By four, boys average about three-quarters of an inch taller and two pounds heavier than girls, with more muscle, while girls carry more fat.
In practice
Two classmates of the same sex, one far taller than the other.
Where people slip
Variation within each sex is far larger than the average difference between them.
