Course Description: The course introduces students to the theory and application of
statistics. Topics include: data description; probability theory; discrete and continuous
random variables and their distributions; sampling distributions; elementary inference
for population means and proportions; Goodness-of-Fit Test; Chi-Squared test for
contingency tables; regression and correlation analysis; and analysis of variance. Note:
Credit can only be obtained in one 100-level STAT course or SOCI 210 or PSYC 211.
Course Objectives: The course provides an introduction to elementary concepts and
techniques from Statistics which have applications to Science, Engineering, Business,
and Social Sciences. Students will become familiar with basic data analysis and learn
how to draw inferences from sample data.
Course Prerequisite: Pure Math 30 or pass the Stat 141 advisory exam.
Course Co-requisite:
None
Required Learning Materials:
Text book: The Basic Practice of Statistics (5th
edition) by David S. Moore, published by Freeman
Other Learning Resources:
Non-programmable scientific calculator
Homework Assignments:
All problems referred to are from the textbook. Your work should be neat and easy to
read. Graders may deduct marks for work that is messy and difficult to follow. Staple
the pages together. The completed homework assignment must be dropped
off in the box labelled “Sunil Barran” near room 5-168 before 4 p.m. on the

Please Note:
1. Official final grades can be accessed through Web Advisor. Grant MacEwan
University adheres to the Alberta Common Grading Scheme, which is a letter
grade system. While instructors may use percentages to aid in their grade
development, only the letter grade will appear on transcripts.
2. A minimum grade of C- is required to receive transfer credit or to satisfy a
prerequisite for a higher level course.
3. In order to obtain a C- or better in the course, a student must obtain a
minimum of 40% on the final examination.
Student Responsibilities:
Students are expected to be aware of their academic responsibilities as
outlined in the Students’ Rights and Responsibilities section in the
University Calendar.
1. ACADEMIC INTEGRITY: All forms of student dishonesty are considered
unacceptable. MacEwan’s Academic Integrity policy (C1000) promotes honesty,
fairness, respect, trust, and responsibility in all academic work. According to the
policy, “Academic dishonesty involves participating in acts by which a person
fraudulently gains or intentionally attempts to gain an unfair academic advantage
thereby compromising the integrity of the academic process”. All incidents of
academic dishonesty are reported and recorded by the Office of Academic
Integrity. The penalties and sanctions for academic dishonesty can include the
following: a mark reduction up to zero on a piece of academic work, a grade
reduction up to an F in the course, and suspension or expulsion (with transcript
3
notation) from the University. Please see the academic policy at
http://www.macewan.ca/web/services/ims/client/upload/C1000%20Aca
demic%20Integrity.pdf for more details. You are responsible for
understanding what constitutes academic dishonesty.
2. REGISTRATION STATUS: You are responsible for your registration status at
the University. Program Advisors may assist you with the process of registration,
including adding or dropping of courses, but it is your responsibility to verify that
these changes have been officially completed. This verification can be done at any
time using Web Advisor. You should check your official registration status before
the last date to officially withdraw from the course.
3. WITHDRAWING FROM THE COURSE: If you stop attending class you
must complete a Course Drop Form, have it signed by a Science Advisor, and
submit it to the Registrar’s Office by the last day to withdraw as provided in the
Academic Schedule in the University Calendar. Failure to officially withdraw will
result in a grade being assigned based on course work completed. Late
withdrawals are only allowed for exceptional circumstances.
4. ATTENDANCE AND PUNCTUALITY: Attend each lecture and lab. Take
notes even you don’t understand fully. Please read the assigned materials before
the lecture. Students are responsible for the
materials covered in the class.
5. EXAMINATIONS: Your student photo I.D. is required at examinations. It is at
the discretion of the instructor whether you will be allowed to write the
examination if you arrive over 15 minutes after the examination has begun. You
must remain in the examination room for at least 20 minutes from the time it
commenced. Electronic equipment (iPods, cell phones, etc.), other than
calculators that have been approved by the instructor, is not allowed to be used
during examinations. Permission to use the washroom during examinations is at
the discretion of the instructor and may require accompaniment.
6. MISSED TERM EXAMINATIONS: If you miss a term examination you must
provide the instructor with an explanation within 24 hours or a mark of zero may
be given. Notification may be provided through e-mail, voice mail, or direct
contact with the instructor. Official documentation as to why the examination
was missed will be needed to assess whether your absence will be excused or not.
If your absence is excused the weight of this examination will be added to the
weight of the final examination in the course. Medical excuses must include the
date you were examined, the specific dates for the period of the illness, a clear
statement indicating that the severity of the illness prevented you from attending
school or work, and the signature of the examining physician (a signature by
office staff on behalf of the physician is not acceptable). Medical notes obtained
subsequent to the date of the examination are generally not accepted. A mark of
zero will be given if the instructor considers the excuse inappropriate or
inadequately substantiated.
7. DEFERRED FINAL EXAMINATIONS: A deferred examination will be
granted if a student misses the final lecture examination for reasons considered
by the Science Department to be unavoidable (deferred examinations do not
apply to term or laboratory examinations). An application for a deferred
examination must be provided to the Science Department no later than two
business days after the date of the missed final examination. Application forms
4
are available from the Science Office and must be submitted with appropriate
documentation. Students should advise the instructor prior to the examination if
they know beforehand that they will be unable to attend the scheduled
examination time. Deferred examinations are granted by a Chair in the Science
Department, not by the course instructor. If you have any questions about the
process please call the Science office at 780 497 5786.
8. LATE ASSIGNMENTS: Medical and other excuses are generally not accepted
as a reason for late assignments as due dates for these assignments are generally
known in advance.
9. CELL PHONES: Cell phones are to be turned off during lectures, laboratories,
seminars, and examinations (except under exceptional circumstances in which
approval has been given by the instructor).
10. STUDENTS WITH DISABILITIES: Students with disabilities who may have
special requirements in this course are advised to discuss their needs with
Services to Students with Disabilities located in the Student Resource Centre. You
should advise the course instructor(s) of any special needs that are identified. See
Policy E3400 Students with Disabilities.
11. STUDENT APPEALS: The University has a policy regarding Student Appeals
(E3103). You should access this policy to become aware of the deadlines and
guidelines that need to be followed if you are appealing a grade or other
University assessment.
12. MYMAIL.MACEWAN EMAIL: All students are given a
<name>@mymail.macewan.ca e-mail address. This e-mail address is available
to the course instructor who may distribute relevant course information or
announcements via e-mail. The Bachelor of Science Program regularly
communicates with the students via e-mail. Check your mymail.macewan.ca email regularly or forward it to an e-mail address you check regularly. If you use email to communicate with your instructor you must use your mymail account.
This is to protect your privacy; if a non-mymail account is used, there is no way
for an instructor to verify the identity of the sender.
13. Calculators: Students can use a non-programmable scientific calculator for
their homework and examinations.
14. Disclaimer: The information in this Course Outline is subject to change; any
changes will be announced and distributed to the class or, if applicable, in the
laboratory
