Once upon a time I conducted a meta-analysis for my prelim. I learned that, while there are programs to calculate overall weighted effect sizes and do the general meta-analysis for you, they are expensive. There's also coding stuff you can do in SPSS and in R, but it was confusing for me. So of course I made my own calculator based on Andy Field's A Bluffer's Guide to Meta-Analysis. You really only need to add the sample size and the effect size (as r) and it calculates the fixed and random effects effect sizes, the CIs, and the ChiSquare statistic. The second excel calculator I have listed is designed to correct the standard error and calculate the failsafe N for your meta-analysis. Feel free to use these, but please cite me.
