Course Overview:
A
course in basic statistics is offered in a wide variety of disciplinesfrom the
social sciences to business to the natural sciences. The same statistical
methods are applied across disciplines. Therefore it should not be surprising
that the tools you will learn to use in this course will benefit you in your
future courses and careers regardless of whether your career interest is
Finance, Accounting, MIS, Management, Marketing, or outside the business realm.
In this course you will learn basic descriptive statistical methods, sampling
methodology, how to draw inferences from samples to larger populations and how
to make predictions based upon historical relationships between variables.
This course has been designated a Quantitative Reasoning flag course
by the University College. Quantitative Reasoning courses are designed to equip
you with skills that are necessary for understanding the types of quantitative
arguments you will regularly encounter in your adult and professional life. You
should therefore expect a substantial portion of your grade to come from your
use of quantitative skills to analyze realworld problems.
My experience has shown that statistics is best taught through a series of clear
and carefully worked examples. Therefore, theoretical background in descriptive
and inferential statistical methods will be provided, however a great deal of
time will be spent teaching you how to apply the theory to the real world.
Statistics is not about memorizing formulas. Instead it is about recognizing the
appropriate statistical test to perform in a given situation. This requires
practice on the part of the student. As we cover the topics, if you do not
have a clear understanding of one topic it is wise to seek help immediately. The
next topic will build upon the previous one. Please allow us to assist you as
soon as you find that you have questions.
Textbook:
Moore, D. S., McCabe, G. P., Duckworth, W. M., & Alwan, L. C. The Practice of
Business Statistics; W. H. Freeman & Company (second edition), 2009. You do
not need to purchase the study guide or any Excel manuals.
Course Packets: Can be purchased at the GSB Copy Center (GSB
3.136)
Notes for Chapters 6, 7, 8 & 9 (these will only be helpful if used during
lecture in class and are not a substitute for coming to class)for use
after Test 1.
Sample Exams 1, 2 & 3
Grading Procedure:
2 Tests and Final Exam:
Test 1 worth 25%; Test 2
worth 25%; Final worth 30%
10 Homework Assignments worth a total of 20% (7 written and 3 using Excel)
Historically, cutoffs for course grades are as follows: A (94), A (90), B+
(87), B (80), C+ (77), C (70), D+ (67), D (60).
Exams and Homework:
There will be 2 tests and a final exam given at designated times during the
semester. They will be multiplechoice and will require computation and
interpretation of the various statistical methods covered in this course. For
the tests and the final exam, you will each be allowed to bring a single 8.5
by 11 inch sheet of paper with any formulas or conceptual items you may need
written on it. You are responsible for deciding what to write on this sheet and
you may write on both sides of it. Sample exams may be found in the course
packets. All exams will be given during regular class time in the regular
classroom.
Written homework to be turned in for a grade will be distributed via email as
we cover each topic. Due dates will be laid out in these emails and also
announced in class although approximate due dates are listed below. When you
turn in these written homework assignments, you will also need to attach your
practice problems from the textbook listed on the class website (see below) and
turn them in as well. These practice problems are graded for completeness only
although you will need to turn them in to receive credit for the graded
homework. In addition, there will be 3 homework assignments using Excel (posted
on the class web page) to be completed and turned in for a grade. Brief explanations
regarding how to perform various statistical tests in Excel are available on the
class web page under the Handouts link, however we will go over some of these
methods in class.
Written Homework should be done neatly with answers circled and all work shown.
Homework will only be accepted in hard copy form and not via email. Homework
not turned in by the time the papers are taken from the classroom at the end of
the 10 AM class (10:50) will be assessed a 10% late penalty. Homework will not
be accepted after 3 PM on the due date. If you wish to turn in a late assignment
and we are not available, please take your paper up to the IROM Office (CBA
5.202) and ask one of the people in the office to write the date and time and
their initials at the top and to put your paper in my mailbox.

Additional Practice
(Essential for the Exams):
Selected written homework problems from the textbook (listed under the Homework
link on the class web page) will also be assigned for exam preparation purposes.
You should do these as we go through the material as this will provide important
practice for the exams and the homework that is to be turned in for a grade.
These must be attached to your homework with each chapter in order to receive
your grade for that chapter. Once these have been turned in, I will post
the solutions under the Homework link on the website.
Your proficiency with statistics will improve with active practice. This means
working problems and understanding and explaining your results. The textbook has
about 100 problems per chapter from which to gain additional practice. Answers
to all oddnumbered problems are given in the back of the textbook.
Other Course Materials:
You will need a calculator for this course to be used with homework and
brought to the tests. A basic calculator that adds, subtracts, multiplies and
divides and finds square root will be sufficient. You may not use a cell
phone to do calculations during the exams. You should also have a recent
version of Microsoft Excel on your computer or you may use the computers in
the Business School labs. This course will be taught utilizing Excel because it
is what you will most likely have available to you in your future work
environment. However, there are a number of statistical procedures that we will
cover in this course that Excel does not readily perform. I will try to point
out to you what Excel will and will not do and any errors in the Excel functions
of which there are a few. For procedures that Excel does not perform, the
publisher of your textbook has provided an additional software package (WHF
Stat) that installs within Excel. We will be using this software to analyze
categorical data later in the semester and you will receive detailed
instructions on how to access it at that time.
Student Responsibility:
The dates on the course outline on this syllabus are approximate and therefore
subject to change. Such announcements will be made in class and sent to you
via email (at your official address listed in Blackboard). You are responsible
for checking this email regularly. While class attendance will not be
taken, students who come to class will receive valuable information during
lecture that will assist in performing well on exams. Good class
attendance along with regular practice is the best way to do well in the class.
Makeup exams will not be given except for a University approved reason.
ADA Accommodations: Compliance with
the Americans with Disabilities Act is a policy of this course. Students with
disabilities may request accommodations from the Division of Diversity and
Community Engagement, Services for Students with Disabilities, 4716259,
http://www.utexas.edu/diversity/ddce/ssd/. If you are entitled to
accommodations please let me know well before the exam by providing your
accommodation letter and discussing with me the particular accommodations you
will need. This will allow me time to make sure that all of your needs can be
met.
Academic Dishonesty:
Dealing with academic dishonesty is a
painful situation for all. Fortunately I have had to do so only rarely in my
twentythree years here. The
College of Business has no tolerance for acts of scholastic dishonesty.
The responsibilities of both students and faculty with regard to scholastic
dishonesty are described in detail in the BBA Program’s Statement on Scholastic
Dishonesty at
http://www.mccombs.utexas.edu/BBA/CodeofEthics.aspx.
By teaching this course, I have agreed to observe all faculty responsibilities
described in that document. By enrolling in this class, you have agreed to
observe all student responsibilities described in that document. If the
application of the Statement on Scholastic Dishonesty to this class or its
assignments is unclear in any way, it is your responsibility to ask me for
clarification. Students who violate University rules on scholastic dishonesty
are subject to disciplinary penalties, including the possibility of failure in
the course and/or dismissal from the University. Since dishonesty harms the
individual, all students, the integrity of the University, and the value of our
academic brand, policies on scholastic dishonesty will be strictly enforced. You
should refer to the Student Judicial Services website at
http://deanofstudents.utexas.edu/sjs/
to access the official University policies and procedures on scholastic
dishonesty as well as further elaboration on what constitutes scholastic
dishonesty.
