Testing Simple Effects in SPSS XXXX

[Dan Abner]

Hello,

I am using the general linear model program in SPSS to analyze data from a
2 x 3 design. What is the best way to perform an analysis of simple effects?

Thank you,

Dan

Simple main effects can be obtained via EMMEANS with COMPARE.  You need something like:

  /EMMEANS=TABLES(A*B) compare(A)

or...

  /EMMEANS=TABLES(A*B) compare(B)

The first one will give the simple main effects of A at each level of B; and the second, the simple main effects of B at each level of A.

Greetings Dan

   I would recommend these web resources for this...

http://www.ats.ucla.edu/stat/spss/faq/sme.htm

and

http://www.ats.ucla.edu/stat/spss/examples/da/daspss11.htm

   The first link provides an overview of performing simple effects analysis, while the
second provides textbook examples based on the book "Design and Analysis" by Geoffrey
Keppel. If you want a good book as a resource for performing such analyses, I recommend
this one highly.

I hope this helps,
