· Chapters 10, 11
· Class syllabus It's pretty much the same as it was for Psychology 317 except that there are four rather than five midterm exams. NOTE that the first exam will be on Wednesday, April 16.
· Textbook errata sheet (same as from Psychology 317, so most of you should already have it)
· Psychology 318 practice exams from 2006, 2008, 2009, and 2010. The general organization is the same as it was for the Psychology 317 practice exams.
· Please go to the same section you went to last quarter (note that the TAs and section times are the same as they were last quarter, but the locations are different).
· Please email me if you did not take Psychology 317 last quarter or if there is a serious problem with your assigned section.
· Please download HW1 assignment from this Excel workbook. NOTE that there are problems from both Chapter 10 and Chapter 11, accessed by tabs at the bottom of the workbook.
· As with previous HW assignments, the problems are mostly from the text but, as specified on the worksheet, there are changes to some of the problems.
· We strongly urge you to do these problems using Excel. Otherwise, they are going to take you forever.
· Chapter 10
· Please download FHW assignment from this Excel worksheet.
· NOTE: It would probably be worthwhile to do these Chapter-10 problems prior to Wednesday's Exam 5 Even though Exam 5 will not cover t-test, many aspects of doing these problems will be relevant to the material that is on Exam 5.
· Please download HW5 assignment from this Excel worksheet, but eliminate Chapter-10 problems. As with previous HW assignments, the problems are mostly from the text but, as specified on the worksheet, there are changes to most of the problems.
· Some of the Chapter-10 problems from the original HW5 will become part of the Final homework (FHW) that will be assigned by tomorrow.
· Please download HW5 assignment from this Excel worksheet. As with previous HW assignments, the problems are mostly from the text but, as specified on the worksheet, there are changes to most of the problems.
I got some questions during office hours about corrections for continuity with inclusive and exclusive probabilities.
Always set up the correction for continuity to capture the values you're interested in. For instance if you have p(5 ≤ X ≤ 9), correct for continuity so as to include the values 5 and 9 by subtracting .5 from 5 and adding .5 to 9. You should end up with 4.5 and 9.5 for your X1 and X2, respectively.
If you're asked to calculate strictly more or less than some number, again consider what values you're interested in and correct for continuity so as to capture these values. If you have p(5 < X < 9), then you're interested in all values between 6 and 8, so correct for continuity to capture these values by setting your X1 and X2 to 5.5 and 8.5, respectively.
· Please download HW4 assignment from this Excel worksheet. As with previous HW assignments, the problems are mostly from the text but, as specified on the worksheet, there are changes to some of the problems.
"Will You Be KILLED By Your Heart Attack?
There is a good chance the heart attack you have will be FATAL!
1 in 3 people will die of heart disease, so the odds are against you."
· Chapter 3, Problem 5: Eliminate doing problems 3, 5, and 8 from Chapter 2
· Eliminate Chapter-5 problems. They will become part of HW4.
· Please download HW3 assignment from this Excel worksheet. As with previous HW assignments, the problems are mostly from the text but, as specified on the worksheet, there are changes to some of the problems.
Here are some mathematical justifications to the Monty Hall solution that some might find easier to understand:
p(B) = 1/3; the chance of the prize being door B
p(~B) = p(A U C) = 2/3 via complement rule
p(A U C) = p(A) + p(C) via addition rule
When door A opens it reveals that p(A) = 0
if p(A) + p(C) = 2/3 and p(A) = 0; it leaves p(C) = 2/3
In the end, with all the information:
p(A) = 0
p(B) = 1/3; staying
p(C) = 2/3; switching
Thus, you should always switch.
· NOTE: There are two worksheets in this workbook: one for Chapter-1 problems, and one for Chapter-2 problems. You can access them by clicking on the tabs at the bottom of the worksheets.
· NOTE: For some of the HW answers you can see the underlying Excel formulas by clicking on the relevant cell. For other answers, you do not see the formulas; you only see the values. This represents our compromise between the conflicting goals of (a) wanting you to be able to see how the answers are computed in Excel, but (b) not wanting this year's answer sheets to be easily useable prior to when the same homework assignment is due in future years.
· Some time ago, I began to write an update to the text that you are using. I haven't gotten very far, but I did write versions of Chapters 1 and 2. They overlap quite a bit both with lecture and with the text that you're using. But they do have some new information and it may be worth your while to read them.
· You can download Chapter 1 here and Chapter 2 here.
· If you detect any errors (which is quite likely) or in general if you have any comments, I'd be very pleased if you emailed them to me. Thanks.
· Please download HW2 assignment from this Excel worksheet. As with HW1, the problems are mostly from the text but, as specified on the worksheet, there are changes to some of the problems.
· Brianna will have her office hours Mondays 2-3:30 pm and Wednesdays 11:30-1:00 pm in the Gould coffee shop. She can be reached at bri52390@gmail.com.
· As indicated on the syllabus, the first exam will be given during class time on Wednesday, 1/15/14, and exams will be given every two weeks thereafter through 3/12/14. To practice for exams, you can download previous exams from from 2006, 2008, 2009, and 2010.
· Note that the folder of exams for a given year contains the exams themselves (as Word documents) plus one "Exam Answers" Excel workbook. Please note: in the "Exam Answers" workbook, the answers to the individual exams are individual worksheets within the workbook that can be accessed by clicking the tabs at the bottom left.
· Please note also that different exams may have covered different materials in different years. It is up to you to figure out which material on any given practice exam is relevant to the exams this year.
· Starting next week, i.e., the week of January 13, Sandrine will hold her office hours in Mary Gates Hall, first floor Commons.
· Sandrine's office hours will be: Wednesdays, 12:30-1:20 and 3:30 - 5:30
· Radha's office hours will be: Mondays and Thursdays, 3:00-4:20

· Brianna Yamasaki has replaced Liz Bird as graduate TA. This will mainly affect students in Liz's section, who will now be students in Brianna's section. I will update the web site soon to provide Brianna's email address and her office hours.
· On Tuesday, January 14 Bobby will switch his office hours to 3:30 - 4:50.
· You can download the final version of the HW1 assignment from this Excel workbook. Note that two problems (5 and 8) have been added, but quite a few have been subtracted
· You can turn in your HW in any way you like to your TA. By default, please turn it in to the "Psychology 317" mailbox in the Guthrie mail room (G128). The mailbox is labeled in orange on the right back wall, facing you, as you enter the mailroom. Within the mailbox are manila envelopes with the names of the TAs. Please place your homework in your TA's envelope.
Should you like to see what happens during the entire 317-318 course, you can access last year's web site here. Note that most of the links will not work, but you can still get an overview of what the course is like.
I'd like you to be circumspect in emailing questions to me. If you have a question that needs an urgent answer, then phone me, stop by, or email me. However, if the question can be answered by a TA, then please direct it to your TA or any TA. If the question can wait, ask someone during office hours, or raise the question in section or in class. Thanks.
This class will be highly Excel-based in that HW assignments, HW answer sheets, and Exam answer sheets will all be posted in the form of Excel workbooks. It is very, very strongly to your advantage to become proficient in Excel. Knowing Excel will allow you, for example, to do your HW assignments faster by at least a factor of 3. It is possible to do well in the course without learning Excel, but it will be considerably more difficult than if you do learn Excel.
· Class syllabus: Please read carefully before coming to the first class lecture.
· Handout packet: I will constantly be referring to these handouts in lectures.
· Textbook errata sheet: Be sure to go through the text and actually implement the errata or you will be confused down the road.
· Preface, Introduction, Chapter 1
· Please download HW1 assignment from this Excel worksheet. Note that mostly the problems are from the text but, as specified on the worksheet, there are changes to some of the problems.
· Note that HW1 is designed to cover only material that I will have covered in class through the lecture on Wednesday, 1/8/14. Because I will not know exactly what this material will be until class ends on Wednesday, there may be some adjustments to the assignment, which I will post very soon after class on Wednesday.
· This adjustment process will be true of all HW assignments. In general, I try to err on the side of initially assigning more rather than fewer problem on a given HW assignment. This means that any Wednesday after-class adjustments usually entail dropping problems. Dropped problems on any given HW assignment will show up as problems on the subsequent HW assignment.
· As indicated on the syllabus, the first exam will be given during class time on Wednesday, 1/15/14, and exams will be given every two weeks thereafter through 3/12/14. To practice for exams, you can download previous exams from from 2006, 2008, 2009, and 2010.
