Formula:

Pearson correlation coefficient ( r ) = Σ [ ( X - My )( Y - Mx ) ] / √ [ ( SSx )( SSy ) ]
Where ,
SSx = Σ ( X - Mx ) 2 SSy = Σ ( Y - My ) 2 X = X Values Y = Y Values Mx = Mean of x values My = Mean of y values Σ ( X - Mx ) , Σ ( Y - My ) = Sum of deviation scores Σ ( X - Mx )2 , Σ ( Y - My )2 = Sum of deviation squared
