X Values ∑ = 419 Mean = 29.929 ∑(X − M_x)² = SS_x = 30.929

X and Y Combined. N = 14 ∑(X − M_x)(Y − M_y) = 29.071

Y Values ∑ = 813. Mean = 58.071 ∑(Y − M_y)² = SS_y = 38.929

R Calculation $r=\text{29}.0\text{71}/\sqrt{\left(30.929\right)\left(\text{38}.\text{929}\right)}=0.\text{8378}$

Meta Numerics (cross-check) r = 0.8378 R = 0.8378 R² = 0.7019
