Variation and Correlation of Oats — Part II 



203 



For average weight of kernels per plant correlated with average height 

 of plant (Figs. 187 to 192), the extreme coefficients are, in line 50, .380 db 

 .037 for series 63, and .718 ± .019 for series 122 — a difference of .338 ± 

 .042, which is about eight times its probable error. In line 62 the extreme 

 coefficients are .450 ± .031 for series 68, and .733 ± .018 for series 102 — 

 a difference of .283 ± .036, or about eight times its probable error.
