Fig. 126. — Correlation between average yield of culm per plant, in deci- 

 grams, subject; and average height of plant, in centimeters, relative 

 r = .801 ± .014 



When average yield of culm per plant is correlated with average length 

 of head per plant (Figs. 127 to 132), the coefficients are not graduated 

 so uniformly in the two lines. The greatest correlation in line 50 occurs 

 in series 122, being here .849 ± .011. This is for the most crowded
