The major objective of this thesis was to study Physical Statistics of Girls according to their physical structure, Maximum Growth Age.
For this purpose the writer surveyed the heights, weights, chest-girth, sitting height of 617 girls of 16 age groups, living in Seoul, and the total 617 girls were randomly selected.
The basic data were obtained from "the student health condition card"in order to longitudinal study.
