Calculation:
X Values
∑ x = 147
Mean = 10.5
∑(X - Mx)2 = SSx = 227.5
Y Values
∑ y = 365.93
Mean = 26.138
∑(Y - My)2 = SSy = 279.099
X and Y Combined
N = 14
∑(X - Mx)(Y - My) = 242.625
Coefficient correlation ,
R = ∑((X - Mx)(Y - My)) / √((SSx)(SSy))
R = 242.625 / √((227.5)(279.099)) = 0.963
correlation coefficient is 0.963
