The SAT scores of 100 students have a mean of 975 and a standard deviation of 105. The GPAs of the same 100 students have a mean of 3.16 and a standard deviation of 0.22. Is the relative variation in SAT scores larger or smaller than that in GPAs? The relative variation in SAT scores is than that in GPAS.
