• Relevant readings for todays lecture are Meehl’s chapter in Lisa Harlow’s (et. al.) edited volume “What if there were no significance tests?” and Will Shadish, Tom Cook, and Don Campbell’s (2002) book that expanded the ideas presented in the Campbell and Stanley monograph. In particular, I would recommend you read chapter 11 in the Shadish, Cook and Campbell book. Unfortunately I do not have an electronic copy of the chapter but there are plenty of copies of the book around the psychology department. Read these two resources if you have the time and interest.

• Relevant readings: You might find Darrel Huff’s “How to lie with statistics” an entertaining read after this lecture. In addition, if you found the lecture to be difficult conceptually, I suggest you carefully consider whether the material in the text and in the lecture will be at or near your current level of knowledge. Catching up at this point may be more difficult than you imagine.

Mid-term Exam 10/23

The exam is an open-book, open-notes exam. Feel free to bring whatever you desire to the exam. As I mentioned in class, the exam is rather long so I suggest you not rely on looking up material during the exam because you will run out of time. Speaking of time, I asked all students present on Monday if everyone could manage to get to the class about 15 minutes before class started (i.e., 1:15pm) and everyone said “yes” so we will begin the exam early. I know some of you were away at conferences but I trust that the 15 minute early start will not be a hardship for anyone. If it is, please let me know right away. Thanks.

• Please read this article for the midterm and be prepared to answer questions related to the topics covered to date that pertain to this article.

• Lecture 8 outline
• Lecture 8 outline with notes

• Midterm summary
• Lecture 9 outline with notes

• Lecture 10 will cover the midterm summary report linked above. Please be sure to read it before the class. I intend to use the summary in our continued discussion of multiple regression.

• Lecture 11 covers ANCOVA and MAN(C)OVA. I suggest you read the chapters before class. In addition, I recommend you read over the this helpful web page. By popular demand, I intend to post the full notes this morning.

Final Exam - details updated after class

• Article: Please read this article and answer the questions I will post below on December 4th, 2006.

• Multiple Choice Exam (December 4th, 1:15pm-4:25pm): The exam will take place in the classroom on December 4th at the usual time we meet for class. I intend to open the doors, hand out the exam at about 1:15pm, and collect the last exam when the subsequent class enters the room.

• Essay Exam (Available: December 4th, 4:30pm, DUE December 13th, 11:59:59pm): The essay exam consists of two comprehensive questions that pertain to the article above. Please be sure to discuss the article in groups but write your own response. Please, please, please, please do not submit identical answers. We already had a bit of a problem with this and I prefer to avoid these problems altogether. Submit your answers to your TA’s via email. Send the responses as attachments or in the body of the message with the subject line reading “611 Final - Essay Questions” without the quotes. Address each of the following questions in detail and limit your responses to no more than 300 words per answer.

1. Explain the rationale of the GLM and how it helps organize the rest of the least squares procedures discussed to date. Be specific about each procedure and make sure you provide enough detail so we know you understand the question. (50 points)
2. In the procedures section under the heading Independent Variable: Skin Tone, the authors state that ratings from two sources were “highly significantly correlated (r = .65, p < .001).” Please explain why this statement does not make sense from what you know about null-hypothesis significance testing. (50 points)
3. Describe the model used to test the primary hypothesis and explain the decisions and possible ramification of the authors choices. (50 points)

• Literature Review (Due December 18th): PLEASE NOTE THE NEW DUE DATE Yes, the due date changed because several students asked me to make the changes to allow them to prepare for the new final exam dates. I agreed that the new date would offer you more time to prepare for the exam and more time to generate a better paper. Please let your advisor know that course grades are due on the 20th so I will need to receive their review grades no later than noon on the 19th in order to submit those grades on time before I leave. Thanks.

Final Exam Results

• Here are the results of the multiple choice section of the final exam. Remember that these points get added to the essay points and then get transfored into a 0–100 scale. I will provide that score for you once the essays are graded and entered. Please look over your exam performance. Anyone interested in seeing their exam results in person is welcome to come by the MRES lab this week. I suggest you come either before 3:30pm on Thursday or between 9am and noon on Friday. Otherwise, you can see the results next week if you are still around.

• The following grading criteria were used to assign points to the essay responses. Please review the following criteria and see how you think you performed on the essay portion of the final exam. Your grades will be posted by the end of the day on Tuesday, December 19th.
