Linear Regression It is believed that the number of units enrolled by a student in a semester causes the average grade of the same student for that semester. Twenty (20) students were randomly selected from CMU and USM and data were gathered from them. Using the simple data: (show your solutions) a. Derive the regression equation b. Solve the coefficient of determination R? and explain. Case # Grade (Y) Units(X) 1 2.46 21 2 1.51 18 2.54 18 4 2.67 16 1.55 16 6. 2.67 18 2.99 20 8 2.8 22 1.25 16 10 1.55 12 11 1.67 16 12 1.56 18 13 1.25 16 14 1.44 18 15 1.88 16 16 1.55 18 17 1.64 16 18 1.92 21 19 1.56 16 20 1.56 16
