Check out this Andy Field paper detailing how to perform a meta-analysis using SPSS. However, I would recommend performing your analysis in R, see the other link
I would also use the metafor package in R, the paper above has a sort of R companion from a book - see below.
Personally I've never done meta-analysis using SPSS. There are specific software for this type of analysis. I suggest using Comprehensive Meta-analysis.
Metafor/R has the benefit of being free. I think the Cochrane's RevMan is free too (http://tech.cochrane.org/revman). A.
in this case it is better to use the open software
Hey Andy! thanks for posting the book chapter 17 on doing Meta in R. Would you please tell me the title of the whole book?
