PAET II. 
Application of Methods. 
(8) I will now proceed to apply the abbreviated method already described to 
the calculation of coefficients of correlation, standard deviations and means, and I 
will begin with Height and Head Breadth. 
First, the following 16-fold table was formed (see Table II., p. 215). 
3000 Criminals. 
Height (feet and inches).

Forming from this a 4-fold table on the principle stated in § 3, we have : —

Here = -010667 a, = -018667. 
Hence from the probability integral tables : 
/( = -013366 ^• = -023400 
log M = 1-2016623, e = -156822, 
and the equation in 6, where r, the coefficient of correlation, = sin 9, is : 
•156822 - ^ -H i ( 000313) 6' - ( 000727) ^ + ( 000313) . 
6 = '156822 = 8° 59' 7" gives a very close solution, and therefore r = -1562, the 
probable error being + -0190.
