Calculating SST, SSM and SSE Suppose a random sample yields these 3 points: (1,-3), (3,15), (8,21). The sample regression equation is 25 y= -1+3x 20 a. First calculate y (the average of y). y = 15 Submit Answer | Tries 0/2 10 b. Now calculate SST. 5 SST = Submit Answer |Tries 0/5 c. Next calculate SSM. 0 1 2 3 4 5 6 7 8 9 SSM = X Submit Answer |Tries 0/5 d. Finally, calculate SSE. You can do it in two ways: one simple and the other involves more calculation.
