· Please bring your students ID for the
final test!!!
· The total scores and final grades for each
student are sent separately to each student via email. If you have
any
questions, please write to me. The following are some statistics on the final
exam, total scores and final
grades:
The
mean for Final is 65.97 for Total Score is 74.68, for Final Grade is 2.996556
(out of 4.0). The max for Final is 93, for Total Score is 90.37, for Final Grade
is 4.0. I curved the Final Grade
according to the rule that people who got scores 0, M-A, M, M+A, 90.37 (M
stands for the mean score, A is the standard deviation) would, correspondingly,
get grades 0, 2.45, 3.0, 3.55, 4.0. For the Final Grade, 2 people from the
interval 1.38~2.0, 10 people from the interval 2.0~3.0, 8 people from the interval
3.0~3.2, 12 people from the interval 3.2~3.6, and 2 people from the interval
3.6~4.0.
