The correlation coefficient is equal to ρ = E [ ( x − x ¯) ( y − y ¯)] σ x σ y Simple enough. So, you need to calculate a few things: The averages of x and y ( x ¯, y ¯ ). The variances of x and y ( σ x 2, σ y 2 ). These use the averages found in the first step. The covariance of x and y. This is the numerator of the equation I gave.
