Three physical items: height, Weight and the girth of the upper right arm, were measured in pupils of a junior high school in Kure City. Comparison was made between these three measurements. Also the change with age and difference due to sex were considered.
The result were as follows:
1) Naturally, these three measurements increase with age, but each mean of measure. ments for girls is superior to that for boys in every age group. As for the increment of each measurement with age, the girth of the upper right arm is the least marked. This is regarded due to the increase of the girth of the right arm being more influenced by the develdpment of subcutaneous fat and muscles than by the diameter of the humerus.
2) Correlations among these measurements, especially that between height and weight and that between weight and girth of upper right arm are considered to be high.
3) From the calculation of coefficients of partial correlation, it was proved that the girth of the upper right arm has more intimate relation with weight than with height.
