Course Description: In this course the following topics are covered: data collection
and presentation, descriptive statistics; probability distributions, sampling distributions
and the central limit theorem; point estimation and hypothesis testing; one-way ANOVA;
Goodness-of-Fit and contingency table; and correlation and regression analysis.
Applications are taken from a broad variety of fields such as biological and medical
sciences, engineering, social sciences and economics.
Note: This course may not be taken for credit if credit has been obtained in any statistics course,
or in SOCI 210 or SOCI 310
Course Objectives: The course provides an introduction to statistical methods and
their applications. There are three main topics: description of data using numerical and
graphical summaries; probability theory; and statistical inference, which deals with
drawing conclusions from sample data in a scientific manner. In the computer lab,
students will learn how to use the software program MINITAB or SPSS as a tool in
statistical analysis. No prior knowledge of computers is assumed or required.
Course Prerequisite: Pure Math 30 or Mathematics 30-1 or Mathematics 30-2 or
successful completion of the statistics gateway exam
The Faculty of Arts and Science strictly adheres to the notion of prerequisites, and University
staff conduct prerequisite checks throughout the term. If it is discovered that you do not have the
appropriate prerequisite for this course, you will be withdrawn by the Registrar’s Office.
Deciding to remain in the course without the prerequisite may result in a significant financial
penalty because you will be responsible for any tuition costs associated with the course up to the
date of the withdrawal. Courses transferred to MacEwan University from another post-

Stat 151 Lab Assignments
The computer software used in the Stat 151 labs is MINITAB or SPSS. No prior
experience with this software is expected. Labs will begin during the second week of
classes (September 9-13) and the first lab session will consist of a basic introduction to
the software. In this session, the software essentials will be discussed and the students
are not required to submit any work. There will be a total of five lab assignments to be
handed in. Before you start working on the lab assignment problems, you should first get
familiar with the lecture materials and with the instructions included in the lab manual.

Please Note:
1. Official final grades can be accessed through My Student System. 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.
3
Stat 151 (AS40)Course Outline, Fall 2013
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
MacEwan University Policy E3101: Student Rights and Responsibilities (found
here).
1.
Academic Integrity: All forms of student dishonesty are considered unacceptable.
MacEwan University Policy C1000: Academic Integrity (found here) 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 Academic Integrity Office. 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
notation) from the University. Please see the academic integrity policy 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 (Rm 6-211) 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 myStudentSystem.
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 Program Advisor (Rm 6-211), and submit it to the Registrar’s
Office by the last day to withdraw as provided in the Academic Schedule in the Academic
Calendar. Failure to officially withdraw will result in a grade being assigned based on course
work completed. Late withdrawals are only allowed in exceptional circumstances.
4. Exams: Your student photo I.D. is required at exams. It is at the discretion of the instructor
whether you will be allowed to write the exam if you arrive over 15 minutes after the exam has
begun. You must remain in the exam room for at least 20 minutes from the time it
commenced. Only calculators approved for use by the instructor may be used during
examinations, which include any laboratory and lecture quizzes. Any devices capable of
external communication, such as cell phones, iPods and blue tooth enabled devices, cannot be
used for exams of any type. Permission to use the washroom during exams is at the discretion
of the instructor and may require accompaniment.
5.
Missed Term Exams: 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 email, 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.
4
Stat 151 (AS40)Course Outline, Fall 2013
A mark of zero will be given if the instructor considers the excuse inappropriate or
inadequately substantiated.
6. Deferred Final Exam: A deferred examination will be granted if a student misses the final
lecture examination for reasons considered by the Bachelor of Science Program to be
unavoidable (deferred examinations do not apply to term or laboratory examinations). An
application for a deferred examination must be provided to the Bachelor of Science Program
no later than two business days after the date of the missed final examination. Application
forms are available from the individual departments within the Bachelor of Science Program
(see Cristina Vocaturo, 780 497 5786, vocaturoc@macewan.ca ), 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 the Chair, Bachelor of Science Program, not by the
course instructor. If you have any questions about the process please contact Program
Services (780 497 4520 or science@macewan.ca) or Cristina Vocaturo, (780 497 5786,
vocaturoc@macewan.ca). For further information please refer to MacEwan University Policy
C2005: Final Assessment (found here) and Policy C2020: Grading (found here). Note that
C2005 states: only a compelling situation such as serious illness, hospitalization, domestic
affliction or religious observance will be considered a valid reason for a student to receive
approval for deferral of a final assessment activity and personal vacations are not a
sufficient reason.
7.
Late Assignments (including laboratory assignments): As due dates for assignments
are known well in advance, medical and other excuses are generally not accepted as a reason
for submitting late assignments.
8. Cell Phones: All cell phones are to be turned off during class and exam periods (except
under exceptional circumstances in which approval has been given by the instructor).
9. 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 (found here).
10. Student Appeals: The University has a policy regarding Student Appeals (E3103, found
here). 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.
11. MyMacewan.ca Email: All students are given a <name>@mymacewan.ca email address.
This email address is available to the course instructor who may distribute relevant course
information or announcements via email. The Bachelor of Science Program regularly
communicates with students via email. Check your macewan.ca email regularly or forward it
to an email address you check regularly. If you use email to communicate with your
instructor, you must use your macewan.ca account. This is to protect your privacy; if a nonmacewan.ca account is used, there is no way for an instructor to verify the identity of the
sender.
12. 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.
13. OTHERS: No programmable calculators are allowed for midterm and final exams; internet
use is not permitted during class; texting is not permitted during class.
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.
