A set of X and Y scores has SSX = 20, SSY = 10, and SP = 40. What is the slope for the regression equation?
4.0
2.0
0.25
0.50
Slope = Y/X = 10/20 = 0.50
To find the slope for the regression equation, we can use the formula:
slope = SP / SSX
Given that SP = 40 and SSX = 20, we can substitute these values into the formula:
slope = 40 / 20 = 2.0
Therefore, the slope for the regression equation is 2.0.
To find the slope for the regression equation, we need to use the formula:
slope = SP / SSX
where SP represents the sum of products of the X and Y scores and SSX represents the sum of squares of the X scores.
Given that SP = 40 and SSX = 20, we can substitute these values into the formula:
slope = 40 / 20 = 2.0
Therefore, the slope for the regression equation is 2.0.
