I can take a maximum of 4 people as undergraduate TAs for this class next year.
If you will be here for both Winter and Spring quarters of 2013, and you are interested in being an undergraduate TA for this class, please come by and see me. Feel free to call or email me to set up an appointment.
Important things to know are these.
· Class times and the class structure will be the same next year as it is this year.
· Skills for being an undergraduate TA include both understanding the class materials and being able to explain them to others.
· Undergraduate TAs are expected to attend all class lectures, hold their own section, hold 3 hours a week of office hours, grade their section's homework, and help grade exams.
· Although it's a lot of work, being an undergraduate TA has a number of advantages: you learn the materials much better, you develop skill as an instructor, you develop a nice relationship with your fellow TA's and you get a letter of recommendation from me which is useful for your future. (Plus, at the end of the year, I take everyone out for a celebratory TA dinner).
· Class credit (I believe Psych 497) is available for being an undergraduate TA.
· Please talk to any of the current TAs to get the best sense of what the job is like.
· Chapter 15 (all).
· Chapter 14, focusing on pp. 560-467. Be sure to ignore the p. 460 section on confidence intervals, and instead read the downloaded sheet about them.
· Chapter 15, focusing on pp. 474-499.
· Chapter 13: all assigned problems
· NOTE: For Chapter 13, Problem 7, please ignore the row totals that were given (it was a mistake that they appeared). Please compute the row totals properly as part of the problem.
· Chapter 14: do problems 2, 3, and 5 as indicated except for computing a confidence interval around the Pearson r.
· Note: In the top (black) section of the Chapter-14 HW4 assignment, some of the parts were cut off . Please re-download from here.
· HW4 problems, from Chapters 13 and 14, are described in the workbook downloadable from here.
· NOTE: For Chapter 13, Problem 7, please ignore the row totals that were given (it was a mistake that they appeared). Please compute the row totals properly as part of the problem.
· Chapter 14
· Chapter 13, especially pp. 418 through the rest of the Chapter.
1. It turns out that what are labeled 2006 Exams 2 and 3 are actually from 2004. As yet, I have not been able to find either the correct 2006 Exams 2 and 3 or the 2004 answer sheet. So although you can certainly do these exams for practice, there is not, at the moment, an answer sheet for them.
2. For 2009, Exam 3, there was an error on the Problem 1c answer (it used the column n rather than the cell n to compute a cell confidence interval). That error has now been corrected if you'd like to re-download the answer sheet.

· HW3 problems, all from Chapter 12, are described in the workbook downloadable from here.
· Chapter 12, review entire chapter
· Chapter 12, pp. 363-387
· Chapter 12
· Problems are described in the HW2 workbook downloadable from here. HW2 consists only of the Chapter-11 problems. The Chapter-12 problems (on the second worksheet) will become part of HW3.
· Note that Chapter 11, Problem 1 has two variants: Problem 1.1 has a small n and Problem 1.2 has a larger n. Please do them both.
· At the suggestion of my TA's, I'm going to implement the practice of providing the answers to one HW question from each chapter soon after the HW is posted. This is the first. You can download one HW2 answer from each of Chapters 11 and 12 here (note that for HW2, only the answer from Chapter 11 is relevant; the answer from Chapter 12 will be relevant for HW2).
· Problems are described in the HW2 workbook downloadable from here. This workbook has two worksheets, corresponding to problems for Chapters 11 and 12.
· UPDATE: it is almost certain that only Chapter-11 problems will be included on HW2 and that the Chapter-12 problems will be in HW3.

· Chapter 11
· Chapter 12, through p. 370
· You can download practice exams from Psychology 318 from 2006, 2008, 2009, and 2010.
· Note that each folder of exams contains the exams themselves (as Word documents) plus one "Exam Answers" Excel workbook. The answers to the individual exams are individual worksheets within the workbook that can be accessed, as described above, by tabs at the bottom left.
· There was some justifiable confusion on the HW1 answer sheet regarding whether Problems 5 and 12 should be done as one-tailed or two-tailed tests. In the book, you are asked to test whether the conditions differ, but in the HW1 answer sheet they were done, incorrectly with directional hypotheses.
· In general, whether you should do a one- or a two-tailed test is governed by the nature of the alternative hypothesis. If the alternative hypothesis is that one condition population mean is greater than the other population mean, then this is a directional alternative hypothesis and a one-tailed test should be done. If the alternative hypothesis is that the two condition population means differ, then this is a nondirectional alternative hypothesis anda two-tailed test should be done.

· Please go to the same TA as you had in Psychology 318. If for some reason you cannot go to that TA's section, please email me and I will switch you.
· Due to any error on my part, Chapter 10, problem 3 in the textbook references Chapter 5 problems 3, 4, 5, and 8, while Chapter 10, problem 3 in the supplement sheet provides data sets for Chapter 5 problems 3, 4, and 6.
·You will get credit for doing this problem either of the reasonable ways: doing C5 problems 3, 4, 5, 8 using the data already in the book for Problems 5 and 8, or doing C5 problems 3, 4, and 6 using the data from the HW1 supplement.
· Problems are described in the HW1 workbook downloadable from here. HW1 consists only of the Chapters-10 worksheet.
· 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: (same as Psychology 317, so you don't need it if you downloaded it last quarter). Be sure to go through the text and actually implement the errata or you will be confused down the road.
· Problems are described in the HW1 workbook downloadable from here. This workbook has two worksheets, corresponding to problems for Chapters 10 and 11.

· The problem in the PHW workbook downloadable from here.
· NOTE: the general instructions on the PHW worksheet were for all the Chapter-10 problems, which you'll get as part of HW1 in Psychology 318. For this one problem, just carry out a hypothesis test (at the .05 alpha level) and compute a 95% confidence interval around the sample mean. Sorry for the confusion.

· The Washington State gay-marriage bill is about to be voted on by the state House. In an article reporting this, KING-5 said,
In a poll of 617 registered voters statewide on landlines and cell phones, KING 5 and SurveyUSA asked specifically, “If the legislature were to approve marriage for same-sex couples, and you were asked to approve or reject the law, how would you vote?” In our poll, 47% said they would approve the law, while 46% said they would reject it; 7% said they weren’t sure. The poll has a margin of error of +/-4%.
· The question: How are the pollsters defining "margin of error"?
· Chapter 6
· We have spent quite a bit of time discussing complaints about some aspects of the Exam-2 grading. We have decided on the "non-double-jeopardy principle" (NDJP) which is: you should only lose points once for one error. So for example, in Exam 2, Problem 2, if you lost points because you constructed your contingency table incorrectly, you shouldn't lose additional points for subsequent answers that were correct based on your incorrect contingency table.
· Based on this principle, there are people who can have their grades adjusted if the NDJP was violated in Problem 2 (as just described) or in Problem 5 (based on ripple effects from an incorrectly computed sum of squares). If you did lose points for either of these two reasons, please see Jung (Problem 2) or Crystal (Problem 5) for a possible re-grading.
· Problems are described in the HW3 workbook downloadable from here. This workbook has four worksheets, corresponding to problems for Chapters 3, 4, 5, and 6. Do problems for Chapters 3, 4, and 5 only; Chapter-6 problems will become part of HW4.
· NOTE 1: Chapter 3, problem 5, refers (among other things) to Chapter 2, problem 7. For Chapter 2, problem 7, convert the grades into numbers, i.e., A = 4; B = 3, etc., down to F = 0. That way you can sensibly compute the requested expected value and variance.
· NOTE 2: Chapter 4, problems 3 and 4: For both problems, assume the additional restriction that all letters in the letter string must be different (we realize that some of you may have done one or both of these problems as they were originally stated. If so, please add a note to that effect, and your TA will not take off any points).

Dear Psychology 317 members: as you've no doubt heard, snow is forecast for tomorrow, 1/18/12, the day of the first exam. So I’d like to make my snow/exam policy clear. Which is: the exam will take place unless the University of Washington is officially closed. Which means: assuming that the University of Washington is open, please plan ahead to make sure that you can be there at 8:30 tomorrow morning.
As a side note, I’ve heard from a couple of students that they haven’t been able to get textbooks. This is a consequence of there being many more students in the class than had been expected. As soon as I arrive at school this morning, I’m going to put a copy of the text on reserve at the OUGL. I’m not sure how long it takes between when I order the text to go on reserve and when it’s available, but I’ll hurry the process as much as I can.
regards, Geoff Loftus
TEXTBOOK UPDATE: I gave one copy of the text to the OUGL reserve desk at about 9:05 this morning (Tuesday, 1/17) and asked them to expedite it as much as possible. Another should be going on reserve with similar instructions around 10:30 this morning.
·You can turn homework to a TA (ideally your TA, but any TA will do)
·You can turn in homework in the Guthrie mail room in the mailbox marked "Psychology 317 with a red label" (located sort of to the lower right of the wall facing you as you enter the room ). If you do this, you will discover manila envelopes in that mailbox. Find the one corresponding to your section/TA and put your homework in that envelope.
· 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 ofice hours, or raise the question in section or in class. Thanks.
·Problems are described in the Excel workbook downloadable from here. This workbook has two worksheets, corresponding to Chapter 1 and Chapter 2. You switch from one worksheet to another via the tabs on the workbook's bottom left.
·HW1 problems are meant to be relevant only to the lectures prior to Exam 1, i.e., to lectures that will be given on January 4, 9, and 11. It is likely that when the January-11 lecture is done, I will not have covered all the materials to which all these problems are relevant. Therefore it is likely that, following the January 11 lecture, I will drop some of these problems. Dropped problems become part of the next homework assignment, i.e., HW2. I do it this way because I have found that it's better to assign more problems and drop some at the last moment than to assign fewer problems and add some at the last moment.
