WebOct 27, 2015 · 2 Answers. Sorted by: 19. S x x is the sum of the squares of the difference between each x and the mean x value. S x y is sum of the product of the difference between x its means and the difference between y and its mean. So S x x = Σ ( x − x ¯) ( x − x ¯) and S x y = Σ ( x − x ¯) ( y − y ¯). Both of these are often rearranged ...
