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 SyllabusThursday 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.

to this page and cannot verify that all links work or change broken
ones any more.

- 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.
