Calculate $\Sigma X Y$ for the following set of scores. \[ \begin{array}{cc} X & Y \\ \hline 1 & 0 \\ 2 & 4 \\ 3 & -1 \\ 5 & -2 \end{array} \]

Step 1 ：Given the sets of scores X = [1, 2, 3, 5] and Y = [0, 4, -1, -2], we are asked to calculate the sum of the product of corresponding elements in the two sets, denoted as \(\Sigma XY\).

Step 2 ：This can be calculated by multiplying each X value with its corresponding Y value and then summing up all the results.

Step 3 ：Doing this, we get: \((1*0) + (2*4) + (3*(-1)) + (5*(-2)) = -5\).

Step 4 ：So, the sum of the product of corresponding elements in the two sets X and Y is \(\boxed{-5}\).
