Statistics 151

General Information

  1. Lab Assignments: There are four lab assignments in Stat 151. The goal of the assignments is to reinforce the concepts discussed in lectures through interesting real-world problems and make students familiar with a statistical software package. Each lab assignment is accompanied by the corresponding data file and lab instructions for the assignment. The due dates of the five lab assignments are given below:

    Due Date
    Introductory Lab
    July 10
    No work to be submitted
    July 17
    Tuesday, July 24, by 2 PM
    July 24 Tuesday, July 31, by 2 PM
    July 31
    Tuesday, August 7, by 2 PM
    August 7 Tuesday, August 14, by 2 PM
  2. Software: The statistical software package StatCrunch will be used in lab assignments. Statcrunch is a web-based statistical application containing all statistical features covered in introductory statistics courses. The software is available to Stat 151 students in two versions: Classic StatCrunch that can be accessed from Stat 151 Labs website (just click on the link "StatCrunch" and enter the password provided by the instructor) and New StatCrunch that can be accessed from MyStatLab website. As Classic StatCrunch uses Java, its performance may be seriusly affected by Java local security settings and should be used only by those students who have no access to MyStatLab.
  3. The New StatCrunch works on all platforms including your desktop, laptop, tablet and phone. Those students who do not use MyStatLab for their homework are encouraged to use Classic StatCrunch on their home computers or in the campus labs: BUS B- 18, BUS B-24, and BUS B-28.

  4. Lab Assistance : There are drop-in lab assistance sessions to help Stat 151 students to complete their lab assignments. Lab assistants will be there to get attending students familiar with StatCrunch and answer any questions related to the labs. No advance sign-up is needed; participants can drop in for part or all of the session. Computers are available on a first-come basis.

  5. The sessions will begin on Tuesday, July 10, 2018. The remaining sessions will be held on Tuesday-Thursday at 15:00-16:00 in CAB 331, CAB 335 and CAB 341. The schedule of Stat 151 drop-in lab assistance sessions is posted at Stat 151Lab Assistance. You may also do your lab assignments in your own time using online instructions available on the website.

    In general, there are two lab sessions to complete each lab assignment. In the first session (Discussion lab, on Tuesdays) the lab assistants will demonstrate StatCrunch features needed in the current lab assignment and clarify lab assignment questions. In the second lab session (Completion lab, on Thursdays) the lab assistants will answer any questions the attending students may have about the assignment.

  6. Introductory Lab: In the first lab session on July 10, you are expected to get familiar with the basic features of StatCrunch that are essential for labs 1-4. Click on the link below to access those instructions: The Introductory Lab: Doing Statistics with StatCrunch. The instructions are very detailed and self-explanatory. You may also attend one of the drop-in lab assistance sessions to have the software demonstrated by a lab TA. You are not required to submit any work for the introductory lab.

  7. Preparation: Before you start working on any lab assignment, you should first get familiar with the lecture material and lab instructions corresponding to the lab assignment. It is not necessary to go over the lab instructions in detail to answer lab assignment questions; you may focus on those parts of the instructions that are relevant to the assignment questions.
  8. Backup: This is your responsibility to keep a backup of your work both on the AICT campus file system (AFS) and on a reliable personal portable data storage device ( ZIP disk or USB Flash Drive) . If you keep your data on your portable storage device only and the device gets damaged or corrupted, you will not be excused!
  9. Protecting your work: Before leaving a workstation in any of the campus labs, students must delete all files saved to the workstation’s hard drive. Note that the deleted files will appear in the Recycle Bin. As long as you haven't emptied the Recycle Bin , your files reside there and can be restored. Therefore, you must empty the Recycle Bin before leaving. If you don’t, another student may submit your lab assignment as their own work.
  10. Lab Submission Procedure: The assignments should be submitted to the wooden boxes outside CAB 331/335 by the due date. There are two slots allotted for Stat 151, each of them labelled with the name of the course instructor. Students should make sure that they put their lab assignment into the slot corresponding to their lecture section.

    Students should submit assignments with a cover sheet that contains only name (with the surname written in all capital letters), course section and lab assignment number. The student ID number should not appear on the cover sheet (FOIPP act). The assignments must be typewritten.

  11. Missed Labs: A student who cannot complete a lab assignment because of an incapacitating illness, severe domestic affliction or other compelling reasons can apply to their course instructor for a transfer of the weight of the missed lab to the final exam. The application should be made within 48 hours of the missed lab assignment due date.
  12. Returning Marked Lab Assignments: Labs will be handed back by the lab TA in class after they are graded. The raw scores for each lab will be posted on eClass. Under the FOIPP act, assignments may not be left in boxes or envelopes outside the instructor's office. Unclaimed assignments will be retained until one month after term grades become official.  After that time, they will be destroyed in compliance with U of A confidential shredding procedures.
  13. Re-evaluation Policy: A student who believes an individual question or lab has been incorrectly marked may request that it be remarked. Such requests should be made by resubmitting this particular lab with a cover page “Remarking Request” explaining in detail your concerns within 7 days of its return date in class. After that, we will not consider remarking or re-evaluating the lab. in your "Remarking Request" you will have to demonstrate that the marker made a mistake in grading or the score for some components assigned by the marker are not consistent with the marking schema posted on the website. If after remarking by the grader, you still think the assignment should be re-considered, then you should contact the instructor directly. Students making a request for a remarking must accept that the resulting mark will become the new mark, whether it goes up or down or remains the same.
  14. Students are urged to familiarize themselves with the provisions of the Code of Student Behaviour at to 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.
