The variations in weight. 



We also here present the distribution series (table 8) and the distri- 

 bution curves (fig. 9 a and b), the computed standard deviation and coef- 

 ficient of variability (table 4), the last one graphically (fig. 10). 



A comparison between the coefficients for heiglit (table i) and for 

 weight confirms the fact, which we know beforehand, that weight is a 

 very much more variable conception. The following comparison of num- 

 bers will give us a general view of this: 



Average coefficient of variability. 



When we now are presenting distribution curves, it would be of 

 interest if this difference in variability was exhibited in a way so it 

 would come to full validity as a really indicative sight impression ^^. 

 The curves have therefore been drawn after the following plan: 



As before stated, the public school has only large enotigh material for distribution 

 curves for the single ages.
