A set of X and Y scores has SS_X = 20,SS_Y = 10,and SP = 40.What is the slope for the regression equation? A)4.0 B)2.0 C)0.25 D)0.50

Question

Quizplus · Accepted Answer

The slope for the regression equation is calculated using the formula slope = SP / SSSx, where SP is the sum of the products of deviations and SSSx is the sum of squared deviations for X. Given SP = 40 and SSSx = 20, the slope = 40 / 20 = 2.0.
