z/8=5/20
Multiply both sides of the equation by 8.
8⋅z8=8⋅520
Simplify both sides of the equation.
z=2

Use the formula (zy)i<span> = (y</span>i<span> – ȳ) / s </span>y<span> and calculate a standardized value for each y</span>i<span>. Add the products from the last step together. Divide the sum from the previous step by n – 1, where n is the total number of points in our set of paired data. The result of all of this is the correlation coefficient </span>r<span>.</span>
