No other reasons will be considered for alternate exam accommodations. Past (or Representative) Evaluative Material: There are practice midterm and final exams posted on eClass. Labs and Lab Assignments (10%): https://eclass.srv.ualberta.ca/portal/ Beyond the information below, it will be assumed you are familiar with all information under the topic “Labs” on eClass. There are 4 typewritten lab assignments to submit. You can find all the lab instructions, assignments, data files, due dates, solutions, and all other related information on the eClass (there is no lab manual). Before you start working on the lab assignment problems, you should first familiarize yourself with the relevant lecture material and go through the lab instructions corresponding to the lab assignment. Software: You will use the statistical software package StatCrunch to complete the lab assignments. You will be required to generate your own StatCrunch output and then answer the questions from the output using your knowledge from class. Statcrunch is a web-based statistical application containing all statistical features covered in introductory statistics courses. The software can be accessed through eClass in any campus lab and from your home computer if you have internet. Lab Instructions & Lab Videos: You are expected to do your lab assignments on your own time using online instructions and videos available on the website. Each lab in eClass contains instructions in text and video form. It is expected that you view these before completing the lab. Lab Assistance: There are no assigned lab sessions in Stat 151. On the week that the lab is due, there are drop-in lab help sessions on Mondays, Tuesdays and Wednesdays for the students to attend. You may ask the lab assistants to clarify lab assignment questions. Each lab help session will start at the beginning of the hour (1200, 1300, and so on). Lab help sessions are scheduled as follows: o Monday: 1400 – 1700 in CAB 341 o Tuesday: 1400 – 1700 in CAB 331 and 341 o Wednesday: 1400 – 1800 in CAB 331 and CAB 341 Introductory Lab: You must work through the Introductory Lab Instructions available on the Stat 151 eClass website. Videos are available to further help your understanding in using StatCrunch. You are not to submit anything from this introduction. It is your responsibility to keep a backup of your work. It is your responsibility to protect your work. Do not leave your work on a university computer. Policy about course outlines can be found in section 23.4(2) of the University Calendar. Disclaimer: Any typographical errors in this Course Outline are subject to change and will be announced in class. Page 3 of 7 Statistics 151 – Course Outline Winter 2015 Submit your lab assignments into the appropriate wooden box on 3rd floor CAB by 0850 (8:50am) on their respective due dates. ***Late or misplaced lab assignments will not be graded and will result in a ZERO recorded for that assignment. No extensions will be granted. You MUST do your own work! Grading Fairness: In order to ensure the fairness of the grading process of labs across all groups marked by different graders, the total score of the four labs for each student may be adjusted by the overall average lab total for all students in the course if significant differences among the groups are found. That means that some totals for individual students may be slightly increased. Homework Assignments (10%): Your homework assignments will be administered through MyStatLab, an online homework assessment system. There are 2 alternatives to access MyStatLab: o MyStatLab access with paid access code You can access MyStatLab through eClass using the access code that comes with your copy of the new textbook or the eBook that you purchase either through the bookstore or online. With the paid access code, you can access MyStatLab at any computers at any locations any time of the day With the paid access code, you have online resources such as hints, step-by-step help, and examples similar to the questions that you are required to complete as part of the homework. To register, refer to the file “MyStatLab Registration for Paid Access Code” available on eClass. NOTE: Solving problems is an excellent way to master the STAT 151 material. In addition to your regular assignments, you are strongly encouraged to attempt a variety of problems from the text. MyStatLab also has a variety of practice problems and quizzes. o MyStatLab access with no-cost-alternative access code You can only access MyStatLab assignments through the university computers at Cameron Knowledge Common. The computers at Cameron Library are available on a first come first serve basis. Please plan to do your assignments ahead in time. It is your responsibility for completing the assigned homework in a timely fashion. No late assignments will be accepted. To register, refer to the file “MyStatLab Registration for No-Cost-Alternative Access Code” available on eClass. There are 15 homework assignments with 3 due dates as follows: o Assignments (Chapters 11 – 13): Friday, January 30, 2015 at 23:59 (11:59pm) o Assignments (Chapters 2 – 9, 14 – 16, 18): Friday, February 27, 2015 at 23:59 (11:59pm) o Assignments (Chapters 19 – 26, 28): Friday, April 10, 2015 at 23:59 (11:59pm) Format: Once you are in MyStatLab, you will be able to see the homework assignments and when a homework is available and due. After an answer is entered on MyStatLab, you will get an instant response as to if your answer is correct. You are allowed unlimited tries for each question, but MyStatLab will give you a new but similar question after enough attempts with incorrect answers. Please complete your homework before the due date. Late assignments will not be accepted. Medical and other excuses are not accepted as a reason for late assignments as due dates for these assignments are known in advance. Within 48 hours of the due time of a homework assignment, any technology/computer problem (unless it is a general problem with MyStatLab that affects all students) will not be accepted as a valid excuse for failing to complete the assignment in time. Please plan to complete the assignments well in advance of the actual due date. If you have an isolated issue, you therefore have plenty of time to resolve it and/or access another computer.

Excused Absence Where the Cause is Religious Belief: For an excused absence where the cause is religious belief, a student must contact the instructor(s) within two weeks of the start of Fall or Winter classes to request accommodation for the term (including the final exam, where relevant). Instructors may request adequate documentation to substantiate the student request. Missed Components: Missed Midterm and Missed Lab Assignments: A student who cannot write the midterm exam or hand in a lab assignment due to incapacitating illness, severe domestic affliction, or other compelling reasons can apply to transfer the weight of the missed component to the final exam. There are no deferred term exams or lab assignments. To apply for a weight transferral, a student must inform the instructor within two working days following the scheduled date of the term work or term exam missed, or as soon as the student is able, having regard to the circumstances underlying the absence. In all cases, instructors may request adequate documentation to substantiate the reason for the absence at their discretion. An excused absence is a privilege and not a right; there is no guarantee that an absence will be excused. Misrepresentation of Facts to gain an excused absence is a serious breach of the Code of Student Behaviour. Missed MyStatLab Homework Assignments: Since the material is covered in class well before the due dates, no excuses are accepted for missing a due date. Missed Final Examination: A student who cannot write the final examination due to incapacitating illness, severe domestic affliction or other compelling reasons can apply for a deferred final examination. Students who failed at the start of term to request exam accommodations for religious beliefs are expected to follow the normal deferred final examination process. Such an application must be made to the student’s Faculty office within two working days of the missed examination and must be supported by a Statutory Declaration or other appropriate documentation (Calendar section 23.5.6). Deferred examinations are a privilege and not a right; there is no guarantee that a deferred examination will be granted. Misrepresentation of Facts to gain a deferred examination is a serious breach of the Code of Student Behaviour. Date: Saturday, May 2, 2015 Time: 0900 – 1200 Location: TBA. Please meet outside of the classroom at 0830 to register for the exam NOTE: Deferral of term work and/or examinations is a privilege and not a right; there is no guarantee that a deferral will be granted. Misrepresentation of Facts to gain a deferral is a serious breach of the Code of Student Behaviour. Reexamination: A student who writes the final examination and fails the course may apply for a reexamination. Reexaminations are rarely granted in the Faculty of Science. These exams are governed by University (Calendar section 23.5.5) and Faculty of Science Regulations (Calendar section 192.5.3). Misrepresentation of Facts to gain a re-examination is a serious breach of the Code of Student Behaviour. Student Responsibilities: ACADEMIC INTEGRITY: ‘The University of Alberta is committed to the highest standards of academic integrity and honesty. Students are expected to be familiar with these standards regarding academic honesty and to uphold the policies of the University in this respect. Students are particularly urged to familiarize themselves with the provisions of the Code of Student Behaviour (online at www.governance.ualberta.ca) and avoid any behaviour which could potentially result in suspicions of cheating, plagiarism, misrepresentation of facts and/or participation in an offence. Academic dishonesty is a serious offence and can result in suspension or expulsion from the University.’ Policy about course outlines can be found in section 23.4(2) of the University Calendar.
