A set of n = 15 pairs of X and Y scores has SSₓ = 10,SSʏ = 40,and SP = 30.What is the slope for the regression equation for predicting Y from X?
A)10/30
B)10/40
C)40/10
D)30/10

Question

Quizplus · Accepted Answer

The slope (b) of the regression equation for predicting Y from X is calculated using the formula b = SP / SSₓ, where SP is the sum of the product of deviations and SSₓ is the sum of squares for X. Given SP = 30 and SSₓ = 10, the slope is 30/10.
