INDIVIDUALS AMD MEASTJBEMEKTS CONSIDERED. 



61 



The relationship between stature and body-weight in the total 

 male (i\T = 136) and the total female (JV*=1Q3) series may now be 

 represented in a different way. 



The straight-line equation connecting weight and stature in the 

 total series are: 



For men w= 70.303+0.777* 



For women w= 60.332+0.721* 



These are represented on the same scale for the two sexes on dia- 

 gram 4. The "mean body-weight" has been calculated for each grade 

 of stature. With less than 150 individuals available for each sex the 

 "averages''' sometimes represent a single individual merely and are 

 extremely irregular. The straight line serves fairly well to smooth them.

3, Relationship between stature and body weight in supplementary series of 

 women. See diagram 2 and text. 



The diagram brings out clearly a point noted above, namely the 

 unfortunate narrowness in the range of variation of stature in our 

 series of women. 



For comparison we have several series of data. First of all may 

 be mentioned Castle's 66 1000 Harvard men gymnasium records with- 

 out clothing which give: 



r =0.704 0.015 



Pearson, 67 working with measurements of 1000 male and 160 female 

 Cambridge students, found : 



For men ............ r =0.486 0.016 



^ _ For women .......... r =0.721 0.026 _
