• Here's a hand-out for partial and semi-partial correlations to include in your stats manual.
• Tonight Stefanie will continue with coverage of multiple regression.
• Skim Chapter 10 and read chapter 15 from Howell for next week.
• Work on updating your stats manuals in lab tonight if you have extra time. The material for Pearson's r and bivariate regression need to be added in the same format as previous sections. I'll put together an outline and post later this week.
• Here's the link to my lab methods website. Scroll down about 1/4 of the page and read the New Yorker article and postscript.   
   
• Here's tonight's simple regression assignment.
• Stef will show you how to conduct an item analysis tonight in lab. She will also run a few regression analyses in PASW.
• If there is time, please spend time checking, in pairs, each others' statistics manuals.

• We'll finish Pearson's r this week and we'll start basic regression.
• For class this week (Nov 1st), complete the following online test: htttp://www.humanmetrics.com/cgi-win/JTypes2.asp
  • Read the following links to learn more about your personality types
  • http://typelogic.com/

• Here's the APA Taskforce's Guidelines along with the published letters to the editor one year later. Print this out and put it in your stats manual or link it as with the other articles. Bring questions/comments to class.
   

• Here's the next checklist for the stats manuals.

• Here's an official copy of Ferguson's paper. Here's another and another paper on effect sizes you should have in your stats manuals.

• Stefanie will demo G*Power with t-tests in tonight's lab. Work problems 8.1, 8.4, 8.6, 8.10, 8.12 in Howell (6th Ed). 

• Work on updating your stats manuals with the checklist I handed out in class.
   

• Stefanie will review dependent and independent samples t-tests in PASW tonight. She'll also show you how to run analyses in OOM.

• Here's the data set for OOM. Here's the article on which the data are based (Study 1). We'll discuss the article next week and finish t-tests.

• Ferguson's paper
  
   
   

• Tonight Stefanie will show you how to conduct single sample and dependent t-tests in PASW.

• Here's the hand-out with the formulas for your stats notebooks.

• The stats notebooks are due next Tuesday during lab. They should include all of the materials in the outline.

• No HW for this week. Spend the time whipping the notebooks into shape.

• APA examples for the z-test and t-tests are posted below.

• Read Ch7 for next week.

• You'll need this OOM file for tonight's lab.
  
   

• Stefanie will show you how to conduct a chi-square test of association in PASW this week.

• For HW, work problems 6.10, 6.14, and 6.16 from Howell (6th Edition). Work each of the problems by hand, being sure to show all of your work, and then checking your results in PASW. Compute Cramer’s V as the effect size estimate for tables larger than 2x2. For 2x2 tables use the odds ratio and its confidence interval. You can ignore Howell's specific questions, just work each example following the steps we learned in class. Report the results for problem 6.16 using APA style.
  
   

• Stefanie will go over the HWs from last week, and we have decided to permit the class to correct their errors on this first assignment to earn back half of the points missed. Please take future assignments seriously and put forth your best effort. If you have questions along the way, ask Stefanie for guidance.
• Here's tonight's assignment.
• Here's an Excel file for the Regression data. You can edit it for tonight's HW.
  
   
• Here's the hand-out from class. It does not contain the figure for the chi-square distribution nor the written annotation. Still, you might find it useful to edit and to add your materials.
• Sorry to spring this on you after the lab, but work problem 6.1 for practice. Work the problem as we did in class, showing all of your computations and interpretations. Be sure to write the hypotheses, test for significance, compute effect sizes, and compute confidence intervals.
  
  
   
• You'll need the following PASW syntax and data file to precisely compute confidence intervals. Save these files for future reference.
• Here's the secure link to the OOM program. Do not save or share the file. Having purchased the book, you can register (http://booksite.academicpress.com/grice/oom) and obtain a licensed copy of the software. You'll also gain access to online resources for the book.
   
•  
• PASW syntax for tonight's lab.
• Read Chapters 1 and 2 in Howell. Work problems 2.10, 2.12, 2.17, 2.18, 2.20, 2.22, 2.26, 2.32, 2.34, 2.36, and 2.38
• Please make sure your homework is done neatly! Organize and clearly label all of your work and answers. If your handwriting is naturally sloppy, then use a word processor. There is simply no excuse for sloppy work, and if I judge your work to be sloppy, I'll deduct half of the points. Put yourself in Stefanie's shoes. It should take her only a few minutes to grade your HW if it is done neatly.
  
   
• Welcome to OSU and to Psyc 5304! If you are looking for the course book, we'll be using Statistical Methods for Psychology (6th Edition) by David C. Howell and my Observation Oriented Modeling: Analysis of Cause in the Behavioral Sciences. 
  I am asking you to purchase these books online or to order them from local retailers. A seventh edition of Howell's book has been published, and an 8th edition may be soon forthcoming. You can purchase one of the newer editions if you'd like, but you can probably find the 6th edition (pictured left) for under 100 dollars new and under 50 dollars used. I will be using the 6th edition in class. My book (pictured right) was recently released and is still a bit pricey. Sorry about that!
  
   
• Be sure to purchase a 'scientific calculator' for the course, which can be obtained from Wal-mart, Walgreens, etc. for ~10 dollars. If you have a Texas Instruments 86, 89, etc. that will do as well.
