Unfortunately, I had to keep a lot of blanks so that the class can be as interactive (viz helpful) as possible. Also, I will be going over some problems which are very similar to some of the HW assignment and exam problems. So, it will be wise for all of you to show up.

November 30, 2009

I have posted the practice question set for Exam 3 in the course webpage. There are only 41 problems (as opposed to 80 or 90 as was the case for Exams 1 and 2)!!! So, just get going and let me know if you have any questions.

November 29, 2009

Hope all of you had a wonderful Thanksgiving break. Its time to return to the Statistical world again!!!
As I did before exam II, I will devote Tuesday's class to answer all your questions regarding Chapters 11 and 15. Please go over my notes and the HW problems and identify the areas where you are stuck. I will try to clarify all your doubts.

November 26, 2009

Unfortunately, there is a small typo in the HW assignment for Chapter 11. Choice (d) of Q 13 would actually be : The odds of being unhappy if you have 0-5 friends is 1.8 times the odds if you have 6 or more friends.
I will post the HW assignment for Chapter 15 as soon as I can. Please let me know if you have any questions.
Have a wonderful Thanksgiving!

Unfortunately, there is a small mistake in the CHAPTER 11 PART I notes. The last line of page 3 will be : "So, for females, the conditional distribution of watching the game is (28%, 32%, 40%)". Sorry for this. Let me know if you have any questions.

November 12, 2009

I have posted the suggested HWs for the stuff we did this week. Please try to do the problems as best as you can. If you have any questions please donot hesitate to see me or the TAs.

November 10, 2009

I have posted the HW grades for Exam II in E-learning. You will now see the grades for HW I (the total of part I and part II) and those from Exam II. You will no longer see the separate part I and part II grades from HW I. You will also see that the TOTAL for both the HWs is 50. So, if you have gotten, say, 55 - that would mean that you have 5 bonus points to your credit.
I have decided to offer the make up exam on Friday sometime in the evening. I think that it would be between 5:00-6:00pm at Griffin Floyd Hall # 230 but I will confirm the exact time and place by Thursday.
This exam is only for those of you who could not take the original exam due to some serious illness. I need to see some signed authorization from a clinic or a doctor substantiating your cause. If you have already given me the documents, that's fine. Otherwise please bring it on Friday.
The exam will be on Chapters 12 and 13 as usual (simple and multiple linear regression). Study the notes, practice questions, suggested HWs and you should be good to go.
Also if you haven't submitted the HW assignment yet, Friday will be the last day to hand it over.
Let me know if you have any questions.

November 9, 2009

I have posted the lecture notes for tomorrow (Chapter 11 Part II). Please print it out and bring to class to save yourself some writing.
I am a little concerned about the current attendence pattern, specifically since I started to post the filled in notes. The stuff that we will be doing for exam III is a bit more conceptual that what we have done till now. So, it will be wise on your part if you show up in class regularly. That way you will have a more clear understanding of the material.
Let me know if you have any concerns,

November 6, 2009

This is just to remind you of the important points about tomorrow's exam.
It will start sharpely at 10:40 and you will have 50 minutes as usual. I won't be late this time. I promise!
It is based on chapters 12 and 13 of the text book (Simple and Mutiple linear regressions).
You will have Z, T and F tables but NO FORMULA SHEETS (because thare are so few formulas in the first place!!).
As usual, you can use any calculators (including the graphing ones) as long as you donot scribble your notes in it.
You have to turn in your homework along with the test. Please print out the pdf file and check the answers in pencil or pen and donot forget to write your name and UFID at the top left. I am not willing to accept answers scribbled in loose pages.
As preparation, I think you have had enough of it already!! READ MY NOTES (everything is in there), go over the suggested HW problems, the actual HW assignment, the review notes and you should be in great shape.
I will be in my office (Griffin Floyd 116 D) today from 5-6pm to answer any last minute questions. Tomorrow Jackson will be in his office from 8:30-10:00.
Last but not the least, THE EXAM IS EASY and I am confident that all of you will do well.

November 1, 2009

I have posted the solutions to the practice problems in the "Exam II" link in the course webpage. Please cross check your answers with the solutions and let me or the TA's know if you have any queries.
Unfortunately, there is a mistake in the solutions to the practice questions. The answer to Q 5. would be (B) instead of (A). Choice (A) would correspond to the case when the slope IS significantly different from 0.
I have posted the hints to the HW Assignment in the "Exam II" link in the course webpage. I have given out as much as I can!! Hope these would help you out.
Please printout the assignment, choose the correct response and turn it in on Tuesday. Please write your name and UFID at the top left.

September 30, 2009

The grades for exam I are posted in E-learning. The statistics are as follows : Mean : 77.6 First Quantile : 65 (i.e 25% of the students scored below 65) Second Quantile : 80 (i.e 50% of the students scored above 80) Third Quantile : 90 (i.e 25% of the students got above 90)
I have posted the histogram of the scores in the "Exam I" link of the course webpage.
Overall, the grades are quite satisfactory. But, some of you could have done a lot better. Well, two thirds of the course still remains to be seen! I am pretty sure that if you work hard enough, you can still salvage the course and get a reasonably good grade at the end. So, DONOT BE DEPRESSED.

September 30, 2009

Hopefully the exam went well. Your scores will be posted by tomorrow at the latest.
A few of you didnot turn in the homework yesterday. You can still turn it in by Friday but as a penalty, the extra credit questions will not be graded.
I have posted the first two parts of Chapter 12 notes in the "Lecture notes" link in the course website. Please print them out and bring to class tomorrow.

September 28, 2009

Tomorrow the exam will start sharpely at 10:40 am and will end at 11:30am.
I have posted the solutions to the even numbered problems in the suggested HW list. Let me know if you have any questions.
There will be only 21 questions in the exam as opposed to 26 which is generally the "3024 tradition" (in 50 mins). So, time or (lack of it) should not be a concern. One of the question will be extra credit. So, if you get everything correct, you will score 105 out of 100 (WOW!!!).
You SHOULD know how to calculate the standard deviation for a set of observations in a calculator. If you donot know, just google it (some students learnt it like that). There may be one question where you will need to calculate it for a very small set of observations (so, it should be very easy).
You have to remember all the stuff which are NOT in the formula sheet I posted. These includes (but are not limited to), the rejection rules with p-values, the formulas for the pooled standard deviataions (chapter 10 part III), multiple comparison confidence intervals (chapter 14 part II), finding F statistics for one and two way ANOVA's etc.
You will be given the formula sheet, z, t and F tables with the exam. So, you donot have to carry any tables with you.
You should submit the HW Assignment (both parts I and II) tomorrow. Just identify the correct choices. You DONOT need to show your work.
Within now and tomorrow please read the lecture notes carefully. Everything is in there. Also, go over the solutions of the practice questions and the suggested HWs.
Graphing and scientific calculators can be used in the exam but saving notes into a calculator and accessing them during an exam is absolutely not permitted.
I will be in the office tomorrow from 9:35 - 10:15 to answer any last minute questions you may have.
I wish you all the best for the exam.

September 25, 2009

I have posted the hints for the HW Assignments in the course webpage. They are in the "Homework Assignments" link. Hopefully these will make your job a little easier!
Try to work out the practice problems as best as you can. I will post the solutions within tomorrow.

September 23, 2009

I have posted the review notes for tomorrow in the "Lecture Notes" link and also in the "Exam I" link I created in the course webpage http://www.stat.ufl.edu/~dbhadra/. Please print out the review notes and bring to class tomorrow.
I have also posted the formula sheet (that you will get with the exam) in the "Exam I" link. All the more complicated formulas are in the formula sheet. You need to remember the rest of the stuff.
Yesterday, we finished off Chapter 14. You will be tested on Chapters 10 and 14 in exam 1. I will not ask any questions specifically from the earlier chapters (chapters 1-9) but since the concepts of confidence intervals, significance tests, p-values etc carry over from chapters 7-9, you may want to review those chapters in case you need to.
I have rephrased Q # 4 and 13 in the HW Assignment II inorder to avoid any confusion. The new version is posted in the "HW Assignments" link in the course webpage. Everything else remains the same.

September 21, 2009

I have posted the lecture notes for chapter 14 Part III. Please print this out and bring to class on Tuesday to save yourself some writing.

I will post the notes for Tuesday by this evening.

September 19, 2009

I have posted the suggested HW problems for Chapter 14 in the course webpage. Please go through these problems because the HW problems will be similar to these.
In calculating the standard deviation, you can use any scientific calculator. Those will give you the value of sd if you put in the numbers. If you want to do it by hand, please look at page 58 in the new and old book for the formula. You can also look at the appendix of my Chapter 2 notes.
If you need help about anything but cannot make it during my office hours, you can visit the TA's or can make an appointment with me during your convenient times. I will try my best to accomodate you.

September 17, 2009

Some of the suggested HW problems donot have the answers at the back of the textbook. I have a solutions manual which contains the answers to all the questions. Once you have done the problems, you can come to my office hours to check your answers.

September 1, 2009

Today we finished off reviewing Chapters 6-7 and just started with Chapter 8 (confidence intervals).
The suggested HW problems for chapters 1, 2, 4, 5, 6, 7 and 8 have been posted in the course webpage. These will NOT be collected but I strongly advice you to go over these problems because the exam problems will resemble these kind of problems.
If you are stuck, please let me (or the TA's) know and we will help you out.

August 31, 2009

I have posted the lecture notes for Chapter 8 (confidence intervals). I plan to go through atleast part of it tomorrow. So, try to print it out and bring to class.

August 27, 2009

We have completed reviewing Chapters 1, 2, 4, 5 and part of 6 (till page number 6) today. Thanks for being with me during those gruelling two periods!
As I said in class, I didn't cover all the minute details of the above chapters, since you are supposed to know these details from STA 2023. But, if you have any questions about the stuff we did, please donot hesitate to visit me or the TA's during our office hours.
I observed today that many of you didn't have the printed notes with you. If you print the notes and bring them to class you will only have to fill up the gaps rather than writing everything from the screen. Thus, you will save a lot of time and energy. So, please try to do that from next class.
If you are having problems with the way I am instructing or if you have suggestions for improvement, please let me know. Your inputs are valuable for me to improve the way I teach.
Have a great weekend! See you all next Tuesday.
