We find, using Sheppard's corrections throughout,

X = 12-7007, y = 124-0467, 
o-^ = 3-0648, (Ty= 6-9083,

X,, = 107-3209, 
aM = 20934, V = "SOSO, r = -294] , 
X^ = -9993, = -9953. 
Hence we deduce from formula (xxii)

.(xxxiii). 
This gives 
Pearson gives 
Hence 
From the formula

-0114. 
-0129. 
S„ = -0191. 
2/ = -0004. 
Hence from formulae (xxvi) and (xxviii) we get 
Sf=-0030, S:, = -0051. 
Hence, finally 
= 0114, E^ = -0020, Ey = -0034, 
while, from the simple formulae (xxiii), (xxvii) and (xxix) we get 
^'^ = •0116, E'i=-0021, ^'-,= -0034. 
These give
