Group Activity (Continuation of Exercise 50) The number
Chapter 1, Problem 1.377(choose chapter or problem)
Group Activity (Continuation of Exercise 50) The number 1.7 that appears in two places in the GPA scaling formula is called the scaling factor (k). The value of k can be changed to alter the curvature of the graph while keeping the points (65, 1) and (95, 4) fixed. It was felt that the lowest D (65) needed to be scaled to (.0, while the middle A (95) needed to be scaled to 4.0. The facultys Academic Council considered several values of k before settling on 1.7 as the number that gives the fairest GPAs for the other percentage grades.
Try changing k to other values between 1 and 2. What kind of scaling curve do you get when k=1? Do you agree with the Baylor decision that k =1.7 gives the fairest GPAs?
