Course Information for STOR 215 (Fall 2012)
Tuesday and Thursday 2:00 - 3:15, in Hanes 120
Registration: Enrollment and registration for
the course is handled by Charlotte Rogers in the Department
Statistics and Operations Research. Ms. Rogers can be
reached at 962.2307, or by email at
firstname.lastname@example.org. The instructor does not have
control over the class rolls. Though the first several
lectures are often crowded, there is usually enough space to
accommodate students interested in taking the course.

Statistics and Operations Research

Mathematics", 7'th Edition, by Kenneth Rosen
Classroom Protocol: Please show up on time, as
late arrivals tend to disturb those already present.
Reading of newspapers and the use of laptops, tablets, and
phones, is not permitted during class. Attendance
will not be taken in class. If you are unable to make a
lecture, see to it that you obtain the notes from someone else
in the class.
Homework policy: Homework assignments will be
posted on the course web page and in most cases will be due once
a week. Assignments will be collected at the beginning of class on the
day they are due, so please be prepared to turn in your homework
at that time.
Each homework assignment will be graded: late/missed homeworks
will receive a grade of zero. In computing a student's
overall homework score for the course, their two lowest homework
scores will be dropped. This latter provision is meant to cover
exceptional situations in which a student is unable to turn in
an assignment due to circumstances beyond his/her control.
Under ordinary circumstances, students are expected to turn in
every homework assignment.
To receive full credit on
the homework assignments, you must clearly label each problem,
neatly show all your work (including your mathematical
arguments), and staple together the pages of each assignment in
the correct order. Please write your name or initials on
each page. You should give a clear account of your reasoning in
English, and use full sentences where appropriate.
You are allowed to discuss
the homework problems with other students, but must prepare each
assignment by yourself. Copying of homework is not allowed. Any
questions regarding the grading of homeworks should first be
addressed to the TA. If you are absent from class when an
assignment is returned, you can get your paper from the TA
during their office hours.
Exams: There will be two in-class
midterm exams, and a comprehensive final examination that will
also be in-class. All exams will be closed book and closed
notes, and without calculators. Tentative exam dates are as
follows. The final exam will be given at the date and time
specified in the official University Final Exam Schedule.
||See University Timetable
Grading: The overall course grade
will be based on the homework assignments and exams, and will be
calculated as follows:
When Midterms 1 and 2 are
returned, a rough correspondence between numerical scores and
letter grades for that
individual exam will be provided. The letter
grades are not a prediction of your final grade. Any
student whose score is in the D or F range should come to the
instructor's office hours. The final course grade is based
on a weighted sum of Homework, Midterm and Final scores (not the alphabetic
grades) using the weights above. Note that the final exam
counts as much as the first and second midterms combined.
Syllabus (tentative): We will cover
material from sections of Chapters 1, 2, 4-6, 10, 11 of the text
and selected material from
other chapters as time permits.
Other Texts: You should feel free to consult
other textbooks regarding the material in the course.
Other books that may be useful are:
Finite and Discrete Mathematics'' by Sheldon Ross
Mathematics'' by L. Lovasz, J. Pelikan, and K. Vesztergombi
Honor Code: Students are expected to adhere to
the UNC honor code at all times. Violations of the honor code
will be prosecuted.
1. Keep up with the reading
and homework assignments. If the reading assignment is
long, break it up into smaller pieces (perhaps one section or
subsection at a time). Keep a pencil and scratch paper on
hand as you read the book, and use these to work out the details
of any argument that is not clear to you.
2. Look over the notes from
the lecture k before attending lecture k+1. This
will help keep you on top of the course material. Ideas
from one lecture often carry over to the next: you will get much
more out of the material if you can maintain a sense of
continuity and keep the ``big picture'' in mind.
3. Read the book carefully
*before* doing the homework. Trying to find the right
section, formula, or paragraph for a particular problem often
takes as much time, and it tends to create more confusion than
it resolves. Each chapter of the book contains many
examples illustrating the ideas presented there. When you
first read the chapter, don't feel as if you need to read
through every example: focus first on the shorter, simpler
examples, and then look at the longer, more complicated examples
4. It is important to know
what you know, but it's especially important to know what you don't know. As you
read over new material in the text or your notes, ask yourself
if you (really) understand it. Keep careful track of any
concepts and ideas that are not clear to you, and make efforts
to master these in a timely fashion, using the class notes, the
text, office hours, study groups, and outside reading if
5. One good way of seeing if
you understand an idea or concept is to write down the
associated definitions and basic facts, without the aid of the
book or your notes, in full, grammatical sentences. Take
special note of how you employ prepositions. It's also
helpful to state the definitions and basic facts out loud -- the
same grammatical criteria apply here. Translating
ideas from mathematics to complete English sentences, and back
again, is an important component of the course, and important
component of mathematical research.
6. Homework plays two
important roles in the course. First, it provides an
opportunity to actively think about, engage with, and learn the
course material. In addition, homework provides feedback
on your understanding of the material. Carefully look over
your corrected homework assignments. Most students do well
on the homework: even if you received a good score, make sure to
note and understand or correct any mistakes you made on the
7. Begin studying for exams
at least one week before they are given. Look over your
notes, homework, and the text. Write up a study guide
containing the main concepts and definitions being covered, and
use this to get a clear picture of the overall landscape of the
material. A study guide for each midterm will be posted
online. For every topic on the study guide, you should
know the relevant definitions, motivating ideas, and at least
one or two examples.
