If you would like to view your final exam, instead of coming to my office hours, please fill out this
form and slip it under my door. I'll email you a scanned copy of your final exam (to the email address specified on the form) and you could look
at your work as long as you need and compare it to the posted solution. As I mentioned before, all appeals should be made in writing, that is via email. Nevertheless, if you feel
that you want to talk to me in person, I'll have office hours on Wednesday, 3/30, 3:00-5:00pm.
3/21/2011
In light of today's appealing session, here is the new appealing procedure:
All requests for appeal should be made in writing, i.e. via email.
If you want to view your final examination, please come during the scheduled office hours, that is this Wednesday 4:00pm-6:00pm and another time to be announced in the beginning of next week.
Appeal requests should be made by the end of the first week of the new quarter, that is by 4/3.
The following are not legitimate reasons to change your final letter grade. Make sure your appeal is not based on them:
I worked very hard during the quarter.
I was ranked XXX before the final and dropped to YYY after.
I'll do additional work.
You should change your grading scheme.
You should change the cut-off values.
You should give B+s.
In other words, to get a certain letter you must be within the right range for the numeric final grade, as posted. That is the only way.
3/18/2011
Some clarifications which concern many of your emails.
I followed more or less the guidelines which I published a few weeks ago, that is about 25% get A and then next 30% get B. We ended up with the top 24% getting an A and the next 32% getting a B. The guidelines are suggestive, definitely not strict and moreover, I am the one that decided on them. The A and B regions include A-,A,A+ and B-,B,B+ respectively.
There were no B+s or A+s. According my judgment, the level of examinations dictates a minimum of 85 for an A and a 75 for a B. To give an A or a B with less than that for your final numeric grade, would have been a pedagogical sacrifice and a compromise in the level that is required in the course. In order to accommodate these lower bounds and at the same time to adhere to the 25%/30% guidelines above, no B+/A+ could be given. In other words, to have about 25% As, I had to put the threshold for A- at 77. This leaves only the 75-77 region for B and no room for B+
Office hours - I understand that many of you will be away next week. It will still be possible to see your final exam and discuss the grades in the beginning of the Spring quarter. I will announce special office hours for that at a later time.
3/17/2011
Final grades are now posted on MyUCLA. Under "Final Numeric Grade" in the "Other" category, you can find you total numeric grade. This was calculated precisely as announced in
the beginning of the course, that is a weighted average of your average homework, average midterm and final exam
grades, after dropping lowest scores (see Grades in the information section).
The cut-offs for determining your final letter grade were defined based on the guidelines I had posted before (again, see Grades). They are:
Final numeric grade is at least
Letter Grade
85
A
77
A-
75
B
67
B-
65
C+
55
C
50
C-
40
D
0
F
These thresholds are strict. If you missed the threshold even by 0.1, you still missed it.
3/17/2011
Appeals. I will hold office hours next week, on Monday 4:00pm-6:00pm and Wednesday 4:00pm-6:00pm for issues concerning grades and to view your final exam.
3/14/2011
The final and its solution can be found under Exams. Note that the wording and order of the problems are a bit different than the version you had.
3/12/2011
HW10 is now posted (essentially all problems for section 12.6.2). No need to submit it.
3/12/2011
Some more notes on the final:
There will be 10 problems, not 12. Each is worth 10pts.
The following are excluded from the midterm: Law of Large Numbers (12.6.1), Joint Distributions (12.4.2),
Multinomial Distribution (12.4.4). I've updated the schedule to reflect
what we have covered in class.
3/12/2011
I've placed your HW9 in a box outside my office. Feel free to go and get it from there.
3/12/2011
Two more exams (midterms) from the previous quarter are now posted under
Practice Resources in the information section.
3/12/2011
The cutoffs for the intermediate grades were: A (>=84), B (>=76), C (>=55) and D/F (<55).
3/11/2011
Review office hours will take place this Sunday, 3/13 at 6:30pm in YOUNG-CS76 (usual room). I will stay as long as I can still stand
(we have the room until 9:30pm).
Midterm 4 grades are now posted. The average was 48.
3/8/2011
Here is the information about the coming final exam (see course information
section for additional info).
Time: Monday, March 14, 2011 between 11:30 AM and 2:30 PM.
Place: MOORE 100.
What to bring: writing utensils only. No notes or electronic devices are allowed. Answers will be written on the exam form.
There will be an empty page at the end of the exam and more sketch paper will be provided if neccessary. The table
of values for the c.d.f. of the standard Normal Distribution will be provided.
Topics included: everything we covered in lectures and discussions, from the first week to the last week. That includes
topics not in the book (e.g. Hypergeometric approximation to Binomial) and excludes topics in the book which were not covered
(e.g. Hazzard rates).
Format: 12 problems. Most problems will have more than one item in them. The first items will be relatively straightforward
(level of book problems) and the last items will be more challenging - level of additional homework problems and midterms.
3/8/2011
Additional sources for practice problems - Per the request of many students, I've added a list of resources under
Practice Resources in the information section. Resources include textbooks
which you can buy at the bookstore as well as exams from previous years. I'll try to provide more old exams, if I
can obtain them on time.
3/8/2011
A review lecture + special office hours will be given during the weekend. Time and place to be announced. Among other things,
I'll go over midterm 4. Note that the last lecture on Friday will be a regular lecture, not a review session and you will
need to know the material taught in it.
3/5/2011
Final answers to problems in HW9 are now posted.
Also, there was a typo in the final answer to problem 12.5.3 in HW8 (the order was wrong).
Note that the last problem in HW7 is also relevant to the midterm.
3/4/2011
Midterm 4 will take place on Monday 3/7. Here are the details (see also the
"Examinations Section" in the course information tab):
The midterm will take place in class, last for 25 minutes and start at 2:25pm.
Material includes: Continuous random variables (12.5.1), the Uniform Distribution (12.5.3),
the Exponential Distribution (12.5.4). Notes:
We did not cover everything that is included in the above sections in the book (e.g. Hazzard rates).
You only need to know what we covered in class.
These topics are covered in lectures up to and including Monday 2/28 and discussion sessions up to and including
the ones on 3/1 and 3/3.
Relevant HWs are: HW8, HW9 and last problem in HW7. I'll put solutions to HW9 over the weekend.
No notes, texts or any electronic devices will be allowed during the midterm.
Solutions will be written on the midterm pages (space will be provided including one for scribbling).
2/28/2011
HW9 is now posted (last one!).
2/28/2011
Typo in page 122 of the lecture notes for week 7 (see handouts section). The Variance of the Hypergeometric distribution should be n*(G/N)*(1-G/N)*(1-(n-1)/(N-1)).
No points will be taken off, if you used the previous formula in HW7.
2/22/2011
The link to the notes of last week's lectures is now fixed.
2/22/2011
Material for the midterm. As many of you had concerns about this, here are a few clarifications:
Continuous random variables are *not* included in the midterm. That is, problems similar to the last one in HW7 (choosing a point at random inside a domain) are excluded.
Note that c.d.f.'s are included, I can ask you to find the cumulative distribution function of a discrete random variable (e.g. problem 12.4.5).
You did not get enough (and sufficiently in advance of the midterm) teaching on the subject of continuous random variables, so we chose to omit this material.
You need to know by heart the formulas for the p.m.f., expected value and variance of the standard discrete distributions (Bernoulli, Binomial, Geometric, Hypergeometric and Poisson).
You need to know both the Binomial approximation to the Hypergeometric distribution and the Poisson approximation to the Binomial distribution.
2/22/2011
Typos in final answers to problems in HW7:
HW7, 12.4.15 - E(Y)=1.2 (not 1), where Y=X^4.
HW7, E(Y)=9.67 (not 6.67), where Y=2X+3 and X~Bin(n=10, p=1/3).
(Thanks to Ramzi, Julie, Shalini for noticing and emailing me).
2/22/2011
In addition to the office hours today between 4:00pm and 6:00pm, I'll have more office hours between 7:15 and 9:00pm. Feel free to drop by. Good luck tomorrow!
