Advanced Statistics

Advanced Statistics

This course is designed to be an intensive investigation into statistical analyses commonly used in Psychology and other social-behavioral sciences. Topics include Factorial ANOVA, Repeated Measures, Multiple Regression, Trend Analysis, Non-Parametric procedures, and the General Linear Model (GLM).

In addition, the student will be exposed to various analytic philosophies. The course will be computer intensive (using SPSS). Students are expected to be familiar with basic statistical issues, though they will be reviewed at the beginning of the class.

The main goals of this course are to: (a) expose the student to advanced statistical techniques, (b) make the student proficient in the techniques, (c) give the student the expertise to “think” about appropriate statistical techniques for the problems they will face in and out of academic settings, and (d) give the student exposure to different analytic strategies and philosophies. This course is associated with select student-learning objectives (linked to Program Goals), including writing skills, critical analysis of research, research skills, applying knowledge to real world problems/applications, and working with others.

This course is analysis and writing intensive. Students usually spend approximately 5-10 hours per week on homework assignments beyond class time.

Tuesday Class Syllabus

Thursday Class Syllabus

PLEASE NOTE: The example data here is taken from the Thursday stats section of my statistics class during the Fall semester of 2012. The actual data in these examples may differ slightly from the data used in your class. Similarly, the syntax matches the data used in their class -- you may need to adjust the name of the variable slightly to match the names used in your class per se. If you were in the Thursday stats class from fall of 2012, you're in luck -- this is exactly what you saw in class.

ALSO, please note that prior to Fall of 2012, Argosy always started the school year on a Monday, so classes that meet twice during the week starts on Thursday. This means that an academic week on this calendar runs from Thursday to Wednesday. That means that for the week of Thanksgiving, it reads "No Class." However, there is no class for the Thursday class, but there is class for the Tuesday class, and they are still finishing up their week.

This class was originally taught using the SPSS software package. However, modifications have been made and all examples have been/will be re-worked using both R and SAS. I hope that in the future I'll also add Stata, though I no longer have access to it; I hope to have it again in the fall of 2013.

  • A link to some old statistics resources I once posted; I no longer have access to this page and cannot verify that all links work or change broken ones any more.

  • SPSS's web page

  • SPSS trial version for download

  • David Howell's Statistical Methods Webpage

  • Andy Fields' Discovering Statistics (aka Webpage

    • For the fourth edition of the text, SAGE Publications put up a site here.

  • R, a commonly used, free statistical software package/language

  • SAS, a commonly used statistical software package (alas, not free)

  • Stata, a commonly used statistical software package (alas, not free)

  • NEW: In my examples of R below, I always use syntax. However, some people don't like syntax. It's possible to make R behave like SPSS. If you JUST can't be bothered by syntax, here's how to make R pretty much just like SPSS (this even includes how to work with an SPSS data set in R when you don't have SPSS but just have an SPSS file). A link to a document by John Fox entitled "Getting Started with the R Commander" is also useful.
