  • 2014-12-12 13:45: Grades have been submitted, and will appear on ROSI after they have been approved. If you have any issues, you must submit an appropriate request through the Registrar's office. We are not allowed to discuss or negotiate grades. If you ask for special consideration, you should not expect to receive a polite reply.
  • 2014-12-11 16:45: I have accounted for all the final exams except for one. This includes people who didn't bubble in their student number, or who bubbled it in wrong, and even people who didn't bubble in either student number or name, but who did write something on the Scantron itself. I have spent much of the afternoon sorting these out. There remains one student who wrote no identifying information on their Scantron at all.

    On Blackboard, you will find a new column called "Final-graded". This should be a checkmark (or a "complete" or something) if I have a final exam mark for you, and blank or incomplete if I don't.

    If this new column is blank for you and you wrote the final exam, you may be the person I mentioned above. If you want to do something other than fail the course, you need to do this: on your question paper, write your name, student number and e-mail address. Clearly indicate your answers for each question. Slide the question paper under my office door (IC 471) by 5:00pm on Monday December 15. Depending on when I submit the grades, I might have to submit a grade with a final exam mark of 0 for you, but if your question paper matches the Scantron I have, I will change your grade later. Be aware that I am doing this as a very special favour. In the real world, if you can't manage to identify yourself, you get zero credit.

  • 2014-12-10 21:00: nothing to see here. Or on Blackboard either, come to that. If you see anything called Total or Weighted Total on Blackboard, it is entirely meaningless. Course grades will appear on ROSI when they are done, which will be in the next few days. If you ask me about things, you will be slowing down the process for everyone, including yourself.
  • 2014-12-01 16:30: Ken is planning to be in his office Thursday 1:00-4:00pm.
  • 2014-11-28 11:30: Ken will be having office hours next Monday 12:00-4:00pm. I have a pile of marking to do next week, but will endeavour to be available on Thursday as well. I will publish times here if this latter is a go.
  • 2014-11-28 11:30: if you're in tutorial 25 and you have any unclaimed quizzes, I (Ken) have them in my office. Get them from me during my office hours.
  • 2014-11-28 11:30: The final exam: this is on Friday December 5th, 2:00-5:00pm in the Gym and AC 223. If your last name starts with A-F (inclusive) you are in AC 223; otherwise, or if you're writing a deferred exam, you're in the (old) Gym.
  • 2014-11-25 12:00 (edited 2014-11-28 11:30): TAs are having pre-exam office hours. The schedule is here. This is "live", and may change as time progresses. TAs are on duty in IC 404. (Note the change: I got this wrong before.)
  • 2014-11-25 12:00: Ken's lecture notes from today are up.
  • 2014-11-24 17:30: Review seminars! See here for dates and times.
  • 2014-11-21 13:30: It is up to you to check your grades as they appear on Blackboard (since that is what I will use to figure out your course grades). If you have a problem with recording of any quiz grades, raise that with your TA at next week's tutorial; if you have a problem with your midterm grade not showing up, e-mail me (Ken). Final deadline for raising any marks issues is Monday December 1 at 4:00pm.
  • 2014-11-21 11:30: Final exam covers chapters 1-25 of the text, but not chapter 22 and not any of the optional sections (marked with a * in the text). Remember that your lectures only had time for the highlights of the chapters, but you are responsible for everything in them (with the exception of the stuff I mention above that is not on the exam).

    The final exam could include anything from the course, but expect to see most of the questions asking about the material from after the midterm exam.

  • 2014-11-21 09:30: Final exam is Friday December 5 14:00-17:00 in the (Old) Gym and AC 223. If your last name begins with A-F (inclusive) you're in AC 223; otherwise, you're in the Gym. (This is the same Old Gym that the midterm was written in.) People writing deferred exams are also in the Gym.
  • 2014-11-21 09:30: course evaluations are open (until December 4). Make sure you have your say, since that's how the course will be better next time.
  • 2014-11-18 12:00: Ken's lecture notes from today up.
  • 2014-11-11 11:30: Ken's lecture notes with today's revisions up. I also did the sample size calculations, which you can review (I finished early so you could attend the Remembrance Day event). Next time, I begin with Chapter 20!
  • 2014-11-10 17:00: I have sorted the pink Scantrons, and almost done the white ones. Some pointers for you to make my job less challenging next time:
    • You need to fill in the circles correctly for your student number, or else your mark doesn't make it to Blackboard.
    • Filling the circles for your name makes it easier for me to check, if your student number isn't properly bubbled.
    • If you don't bubble in the circles either for your student number or for your name, I have to find your exam by hand, and try to match it up to the unlabelled ones in my spreadsheet of marks. This is very time-consuming.
    • Write your name, so I can read it, in the boxes above where you bubble it. If you don't, I have to do it before I can sort the Scantrons.
    Some instructors deduct marks for failing to do any of these things. I don't (at least, not now), but I am seriously considering doing so in the future. This is because not doing these things wastes my time that I could be spending on teaching you better.
  • 2014-11-06 11:00: Exam answers by question are done. Before you search for yourself, read this carefully: I am not allowed to post entire student numbers on the web, so I had to scramble the student numbers before posting them. Here's how to scramble yours: take the last 5 digits, and add to that however many remaining digits there are in your student number. For example, if your student number is 991234567, the last 5 digits are 34567, to which I add the remaining digits, 9912, to get 44479. If your student number starts with a 100, you'll have two five-digit numbers to add together. For example, 1009876543 becomes 76543+10098=86641. Got it? Good. All right, here are the pink exam answers, and here are the white exam answers.

    Here's how to read the files, in case you're not clear: the first column is just a row number. The second column is your scrambled student number, with (for no reason) two unneeded decimal places. After that are the answers recorded for you for each question. If your answer was correct, it's marked with a *; if not, the right answer is shown in brackets after yours. Thus C* means your answer was C and it was correct; B(D) means you answered B but the right answer was D. The number of *'s on your line, which is the number of correct answers, should equal your mark on Blackboard. I checked these and found that they all agreed. If you think yours doesn't, count again.

    I will be getting the original Scantrons in the next day or two. When I have them (which I don't as you read this), you can come and look at (but not take away) yours, during my office hours. A reason to do this would be if you thought the wrong answer had been read from your Scantron. This doesn't happen often, but if you change your mind and don't erase your first answer well enough, the machine might not figure it out.

  • 2014-11-06 10:00: Boxplot of midterm marks, out of 40. Median 24, quartiles 20 and 29:
  • 2014-11-05 19:00: midterm marks are up on Blackboard. Some of you didn't bubble your student number correctly, which I fixed if I could (that is to say, if you bubbled something for a student number and enough of your name to be recognizable). If your mark is missing and you think it should be there, you need to email me (Ken) your name, student number and exam version, and I will try to find you.

    Coming up soon (hopefully): answers by question for everybody.

  • 2014-11-04 11:00: I fixed the problem that was making the exam answers inaccessible. Also, Ken's notes with additions and alterations from today's class are now up.
  • 2014-11-03 15:00: The midterm exams with answers: white and pink. I expect to get the marks tomorrow.
  • 2014-10-31 14:00: Ken's updated notes are up, or possibly even Ken's up notes are updated. Take your pick.
  • 2014-10-28 14:15: the midterm mini-presentation from Ken's class today (this applies to other sections as well). Use space bar or arrow keys to scroll through it.
  • 2014-10-28 11:30: Ken's updated lecture notes uploaded. I filled in the last example as well, which I didn't have time to get to in class.
  • 2014-10-24 15:30: Ken's updated lecture notes uploaded (sorry for delay).
  • 2014-10-21 11:30: Ken's updated lecture notes uploaded.
  • 2014-10-20 17:30: Here's who is where for their exam, by first letter of last name:
    • A: S 143
    • B-SHE: (old) Gym (in the R wing)
    • SHI-V: S 309
    • W-Z: S 319
    The rooms are almost at capacity, so that if you show up at the wrong room for your exam, you will be sent to the correct one, and you will not receive extra time for your exam.
  • 2014-10-20 17:30: The TAs are having office hours before the midterm exam. Check here to find out when they will be on duty. They will be in IC 404. To see the whole schedule, click on the "crinkled" bit between dates.

If you bought a used textbook, you won't (the access code can only be used once). But you can buy access separately, as below:
    • StatCrunch: go here, click on Students Buy Access.
    • MyStatLab and e-textbook: go here. Enter a course ID in the box (Ken's one is butler33143), create a Pearson login (or log in with one that you already have), Use a Credit Card or PayPal.
  • Facilitated Study Groups as below:
    1HarrishTue 16:00-17:00AC 221
    2TharshikaWed 09:00-10:00M 170
    3HarrishFri 11:00-12:00AC 221
    4TharshikaFri 12:00-13:00AC 221
    These sessions are optional, but students have found them helpful. (You only need to go to one, since all the sessions cover the same ground.)

    Note also that the Academic Advising and Careers Centre offers study skills services. There will be a short announcement about that in class on Tuesday.

  • 2014-09-07 20:00: Are you in Tutorial 26? If so, note that there is no TA available for tutorial 26 on Monday Sep 8 only. For week 2 of classes, attend any tutorial that fits your schedule (you don't need to enrol). For week 3 of classes and beyond, tutorial 26 will run in its booked time and place.
  • 2014-09-05 11:30: today's notes for Ken's section are up (see above left).
  • 2014-09-02 11:35: For the second lecture (Thursday or Friday, depending on your section), read chapter 1 (very short) and chapter 2 of the textbook.
  • 2014-09-02 11:30: If you haven't signed up for a tutorial yet, make sure you do. There are some spaces left (not many): the faster you do this, the better your chances of getting a time that suits you. There is (or will be) space for everyone to be in a tutorial.
  • 2014-09-02 09:30: First lectures in all lecture sections are today!
