Given that a set of n = 5 pairs of x and y scores has sx = 15, sy = 5, and sxy = 10.

For this set of data, the value of SP is given by:

$SP=\Sigma XY-(\Sigma X\Sigma Y)/(n) \\ \\ =10- (15*5)/(5) =10-15 \\ \\ =-5$

A set of n = 5 pairs of x and y scores has sx = 15, sy = 5, and sxy = 10. for these data, what is the value of sp?
