Course Grades
Your final grade will be based on total 100 points performance. The
letter grades A, B, C, D will approximately correspond to 90%,
80%, 70%, 60%, respectively. A total grade under 50% will
definitely constitute an F.

Policies
Every student enrolled in this course must follow the
Student
Code. Following are policies specific to the course.
Homeworks
Collaboration is not allowed
for homework under any circumstance.
Data analysis in homework problems must
be done with R regardless of what is specified in
the problems.
No late homeworks will be accepted
Exams
The exams are open-book and open-notes.
Make sure to bring calculators in order to solve data
analysis problems in the exams.
Except for medical emergencies with appropriate documents from
doctor, no make-up exams will be given;
If you have a conflict that will not allow you to take the
exam as scheduled, you must notify your instructor at least
two weeks in advance; and if you need
to reschedule, you will have to take the exam before the
scheduled date.
For both homeworks and exams
Presentation is important in order for your solutions to receive
full credit. Points will be deducted for messy and illegible
answers. Make sure to staple all the pages together and in
order the grader can only grade pages he/she has! Make
sure you staple all the pages together and in order and print
your name legibly on the first page.
