A set of X and Y scores has SSX = 10, SSY = 20, and SP = 8. What is the slope for the regression equation?
To find the slope for the regression equation, we need to use the formula:
slope = SP / SSX
Where SP is the sum of products of deviations from the means for both X and Y scores, and SSX is the sum of squares for X scores.
In this case, you are given that SP = 8 and SSX = 10. We can now substitute these values into the formula:
slope = 8 / 10
simplifying, we find:
slope = 0.8
Therefore, the slope for the regression equation is 0.8.
